perf: optimize build-registry script for ~3.4x faster builds

- Add parallel style building with concurrency limiter (6 concurrent)
- Cache registry imports to avoid duplicate validations
- Pre-load all style maps in parallel
- Process files within each style concurrently
- Batch prettier formatting into single call at end
- Parallelize cleanup of temp files and directories
- Parallelize RTL example generation
- Add build timing output

Reduces build time from ~33s to ~10s.

+## Overview
+
+RTL is a feature that allows you to display content from right to left.
+
+## Sidebar
+
+If you have an existing `sidebar.tsx` component and want to make it RTL compatible, you'll need to make the following changes:
+
+### 1. Update the side prop type and default
+
+```tsx
+function Sidebar({
+  side = "inline-start", // [!code highlight]
+  variant = "sidebar",
+  collapsible = "offcanvas",
+  className,
+  children,
+  ...props
+}: React.ComponentProps<"div"> & {
+  side?: "left" | "right" | "inline-start" | "inline-end" // [!code highlight]
+  variant?: "sidebar" | "floating" | "inset"
+  collapsible?: "offcanvas" | "icon" | "none"
+}) {
+```
+
+### 2. Update the mobile Sheet side prop
+
+The Sheet component only accepts physical `left` or `right` values, so map the logical values:
+
+```tsx
+<SheetContent
+  side={side === "inline-start" || side === "left" ? "left" : "right"}
+  // ...
+>
+```
+
+### 3. Normalize the data-side attribute
+
+The `data-side` attribute is used by CSS selectors, so normalize it to physical values:
+
+```tsx
+<div
+  data-side={side === "inline-start" || side === "left" ? "left" : "right"}
+  // ...
+>
+```
+
+### 4. Update the sidebar container positioning
+
+Change the conditional logic to include `inline-start` and use logical positioning classes:
+
+```tsx
+className={cn(
+  "fixed inset-y-0 z-10 hidden h-svh w-(--sidebar-width) md:flex",
+  side === "left" || side === "inline-start"
+    ? "start-0 group-data-[collapsible=offcanvas]:start-[calc(var(--sidebar-width)*-1)]"
+    : "end-0 group-data-[collapsible=offcanvas]:end-[calc(var(--sidebar-width)*-1)]",
+  // ...
+)}
+```
+
+### 5. Update SidebarRail classes
+
+Replace physical positioning classes with logical equivalents:
+
+| Before                            | After                             |
+| --------------------------------- | --------------------------------- |
+| `group-data-[side=left]:-right-4` | `group-data-[side=left]:-end-4`   |
+| `group-data-[side=right]:left-0`  | `group-data-[side=right]:start-0` |
+| `after:left-1/2`                  | `after:start-1/2`                 |
+| `after:left-full`                 | `after:start-full`                |
+| `-right-2`                        | `-end-2`                          |
+| `-left-2`                         | `-start-2`                        |
+
+### Usage
+
+After these changes, you can use the sidebar with logical side values:
+
+```tsx
+// LTR: sidebar on the left, RTL: sidebar on the right
+<Sidebar side="inline-start" />
+
+// LTR: sidebar on the right, RTL: sidebar on the left
+<Sidebar side="inline-end" />
+
+// Physical values still work for explicit positioning
+<Sidebar side="left" />
+<Sidebar side="right" />
+```

+
+### New CLI
+
+I've been working on a new CLI for the past few weeks. It's a complete rewrite. It comes with a lot of new features and improvements.
+
+### `init`
+
+```bash
+npx shadcn@latest init
+```
+
+When you run the `init` command, you will be asked a few questions to configure `components.json`:
+
+```txt showLineNumbers
+Which style would you like to use? › Default
+Which color would you like to use as base color? › Slate
+Where is your global CSS file? › › app/globals.css
+Do you want to use CSS variables for colors? › no / yes
+Where is your tailwind.config.js located? › tailwind.config.js
+Configure the import alias for components: › @/components
+Configure the import alias for utils: › @/lib/utils
+Are you using React Server Components? › no / yes
+```
+
+This file contains all the information about your components: where to install them, the import paths, how they are styled...etc.
+
+You can use this file to change the import path of a component, set a baseColor or change the styling method.
+
+```json title="components.json" showLineNumbers
+{
+  "style": "default",
+  "tailwind": {
+    "config": "tailwind.config.ts",
+    "css": "src/app/globals.css",
+    "baseColor": "zinc",
+    "cssVariables": true
+  },
+  "rsc": false,
+  "aliases": {
+    "utils": "~/lib/utils",
+    "components": "~/components"
+  }
+}
+```
+
+This means you can now use the CLI with any directory structure including `src` and `app` directories.
+
+### `add`
+
+```bash
+npx shadcn@latest add
+```
+
+The `add` command is now much more capable. You can now add UI components but also import more complex components (coming soon).
+
+The CLI will automatically resolve all components and dependencies, format them based on your custom config and add them to your project.
+
+### `diff` (experimental)
+
+```bash
+npx shadcn diff
+```
+
+We're also introducing a new `diff` command to help you keep track of upstream updates.
+
+You can use this command to see what has changed in the upstream repository and update your project accordingly.
+
+Run the `diff` command to get a list of components that have updates available:
+
+```bash
+npx shadcn diff
+```
+
+```txt
+The following components have updates available:
+- button
+  - /path/to/my-app/components/ui/button.tsx
+- toast
+  - /path/to/my-app/components/ui/use-toast.ts
+  - /path/to/my-app/components/ui/toaster.tsx
+```
+
+Then run `diff [component]` to see the changes:
+
+```bash
+npx shadcn diff alert
+```
+
+```diff /pl-12/
+const alertVariants = cva(
+- "relative w-full rounded-lg border",
++ "relative w-full pl-12 rounded-lg border"
+)
+```
+
+---
+
+### Theming with CSS Variables or Tailwind Colors
+
+You can choose between using CSS variables or Tailwind CSS utility classes for theming.
+
+When you add new components, the CLI will automatically use the correct theming methods based on your `components.json` configuration.
+
+#### Utility classes
+
+```tsx /bg-zinc-950/ /text-zinc-50/ /dark:bg-white/ /dark:text-zinc-950/
+<div className="bg-zinc-950 dark:bg-white" />
+```
+
+To use utility classes for theming set `tailwind.cssVariables` to `false` in your `components.json` file.
+
+```json {6} title="components.json" showLineNumbers
+{
+  "tailwind": {
+    "config": "tailwind.config.js",
+    "css": "app/globals.css",
+    "baseColor": "slate",
+    "cssVariables": false
+  }
+}
+```
+
+#### CSS Variables
+
+```tsx /bg-background/ /text-foreground/
+<div className="bg-background text-foreground" />
+```
+
+To use CSS variables classes for theming set `tailwind.cssVariables` to `true` in your `components.json` file.
+
+```json {6} title="components.json" showLineNumbers
+{
+  "tailwind": {
+    "config": "tailwind.config.js",
+    "css": "app/globals.css",
+    "baseColor": "slate",
+    "cssVariables": true
+  }
+}
+```
+
+---
+
+### Base color
+
+You can now configure the base color for your project. This will be used to generate the default color palette for your components.
+
+```json {5} title="components.json" showLineNumbers
+{
+  "tailwind": {
+    "config": "tailwind.config.js",
+    "css": "app/globals.css",
+    "baseColor": "zinc",
+    "cssVariables": false
+  }
+}
+```
+
+Choose between `gray`, `neutral`, `slate`, `stone` or `zinc`.
+
+If you have `cssVariables` set to `true`, we will set the base colors as CSS variables in your `globals.css` file. If you have `cssVariables` set to `false`, we will inline the Tailwind CSS utility classes in your components.
+
+---
+
+### React Server Components
+
+If you're using a framework that does not support React Server Components, you can now opt out by setting `rsc` to `false`. We will automatically append or remove the `use client` directive when adding components.
+
+```json title="components.json" showLineNumbers
+{
+  "rsc": false
+}
+```
+
+---
+
+### Styles
+
+We are introducing a new concept called _Style_.
+
+_You can think of style as the visual foundation: shapes, icons, animations & typography._ A style comes with its own set of components, animations, icons and more.
+
+We are shipping two styles: `default` and `new-york` (with more coming soon).
+
+<Image
+  src="/images/style.jpg"
+  width="716"
+  height="402"
+  alt="Default vs New York style"
+  className="mt-6 overflow-hidden rounded-lg border"
+/>
+
+The `default` style is the one you are used to. It's the one we've been using since the beginning of this project. It uses `lucide-react` for icons and `tailwindcss-animate` for animations.
+
+The `new-york` style is a new style. It ships with smaller buttons, cards with shadows and a new set of icons from [Radix Icons](https://icons.radix-ui.com).
+
+When you run the `init` command, you will be asked which style you would like to use. This is saved in your `components.json` file.
+
+```json title="components.json" showLineNumbers
+{
+  "style": "new-york"
+}
+```
+
+### Theming
+
+Start with a style as the base then theme using CSS variables or Tailwind CSS utility classes to completely change the look of your components.
+
+<Image
+  src="/images/style-with-theming.jpg"
+  width="716"
+  height="402"
+  alt="Style with theming"
+  className="mt-6 overflow-hidden rounded-lg border"
+/>
+
+---
+
+### Exit animations
+
+I added exit animations to all components. Click on the combobox below to see the subtle exit animation.
+
+<ComponentPreview name="combobox-demo" className="[&_.preview]:items-start" />
+
+The animations can be customized using utility classes.
+
+---
+
+### Other updates
+
+### Button
+
+- Added a new button size `icon`:
+
+<ComponentPreview name="button-icon" />
+
+### Sheet
+
+- Renamed `position` to `side` to match the other elements.
+
+<ComponentPreview name="sheet-side" />
+
+- Removed the `size` props. Use `className="w-[200px] md:w-[450px]"` for responsive sizing.
+
+---
+
+### Updating your project
+
+Since we follow a copy and paste approach, you will need to manually update your project to get the latest changes.
+
+<Callout className="mt-4">
+  Note: we are working on a [`diff`](#diff-experimental) command to help you
+  keep track of upstream updates.
+</Callout>
+
+<Steps>
+
+### Add `components.json`
+
+Creating a `components.json` file at the root:
+
+```json title="components.json" showLineNumbers
+{
+  "style": "default",
+  "rsc": true,
+  "tailwind": {
+    "config": "tailwind.config.js",
+    "css": "app/globals.css",
+    "baseColor": "slate",
+    "cssVariables": true
+  },
+  "aliases": {
+    "components": "@/components",
+    "utils": "@/lib/utils"
+  }
+}
+```
+
+Update the values for `tailwind.css` and `aliases` to match your project structure.
+
+### Button
+
+Add the `icon` size to the `buttonVariants`:
+
+```tsx {7} title="components/ui/button.tsx" showLineNumbers
+const buttonVariants = cva({
+  variants: {
+    size: {
+      default: "h-10 px-4 py-2",
+      sm: "h-9 rounded-md px-3",
+      lg: "h-11 rounded-md px-8",
+      icon: "h-10 w-10",
+    },
+  },
+})
+```
+
+### Sheet
+
+1. Replace the content of `sheet.tsx` with the following:
+
+```tsx title="components/ui/sheet.tsx" showLineNumbers
+"use client"
+
+import * as React from "react"
+import * as SheetPrimitive from "@radix-ui/react-dialog"

+title: July 2023 - JavaScript
+description: JavaScript version of components available via the CLI.
+date: 2023-07-04
+---
+
+This project and the components are written in TypeScript. **We recommend using TypeScript for your project as well**.
+
+However we provide a JavaScript version of the components, available via the [cli](/docs/cli).
+
+```txt
+Would you like to use TypeScript (recommended)? no
+```
+
+To opt-out of TypeScript, you can use the `tsx` flag in your `components.json` file.
+
+```json {10} title="components.json" showLineNumbers
+{
+  "style": "default",
+  "tailwind": {
+    "config": "tailwind.config.js",
+    "css": "src/app/globals.css",
+    "baseColor": "zinc",
+    "cssVariables": true
+  },
+  "rsc": false,
+  "tsx": false,
+  "aliases": {
+    "utils": "~/lib/utils",
+    "components": "~/components"
+  }
+}
+```
+
+To configure import aliases, you can use the following `jsconfig.json`:
+
+```json {4} title="jsconfig.json" showLineNumbers
+{
+  "compilerOptions": {
+    "paths": {
+      "@/*": ["./*"]
+    }

+title: December 2023 - New Components
+description: Carousel, Drawer, Pagination, Resizable, Sonner, and CLI updates.
+date: 2023-12-22
+---
+
+We've added new components to shadcn/ui and made a lot of improvements to the CLI.
+
+Here's a quick overview of what's new:
+
+- [**Carousel**](#carousel) - A carousel component with motion, swipe gestures and keyboard support.
+- [**Drawer**](#drawer) - A drawer component that looks amazing on mobile.
+- [**Pagination**](#pagination) - A pagination component with page navigation, previous and next buttons.
+- [**Resizable**](#resizable) - A resizable component for building resizable panel groups and layouts.
+- [**Sonner**](#sonner) - The last toast component you'll ever need.
+- [**CLI updates**](#cli-updates) - Support for custom **Tailwind prefix** and `tailwind.config.ts`.
+
+### Carousel
+
+We've added a fully featured carousel component with motion, swipe gestures and keyboard support. Built on top of [Embla Carousel](https://www.embla-carousel.com).
+
+It has support for infinite looping, autoplay, vertical orientation, and more.
+
+<ComponentPreview name="carousel-demo" />
+
+### Drawer
+
+Oh the drawer component. Built on top of [Vaul](https://github.com/emilkowalski/vaul) by [emilkowalski](https://twitter.com/emilkowalski).
+
+Try opening the following drawer on mobile. It looks amazing!
+
+<ComponentPreview name="drawer-demo" />
+
+### Pagination
+
+We've added a pagination component with page navigation, previous and next buttons. Simple, flexible and works with your framework's `<Link />` component.
+
+<ComponentPreview name="pagination-demo" />
+
+### Resizable
+
+Build resizable panel groups and layouts with this `<Resizable />` component.
+
+<ComponentPreview name="resizable-demo-with-handle" />
+
+`<Resizable />` is built using [react-resizable-panels](https://github.com/bvaughn/react-resizable-panels) by [bvaughn](https://github.com/bvaughn). It has support for mouse, touch and keyboard.
+
+### Sonner
+
+Another one by [emilkowalski](https://twitter.com/emilkowalski). The last toast component you'll ever need. Sonner is now availabe in shadcn/ui.
+
+<ComponentPreview name="sonner-demo" />
+
+### CLI updates
+
+This has been one of the most requested features. You can now configure a custom Tailwind prefix and the cli will automatically prefix your utility classes when adding components.
+
+This means you can now easily add shadcn/ui components to existing projects like Docusaurus, Nextra...etc. A drop-in for your existing design system with no conflict.
+
+```tsx /tw-/
+<AlertDialog className="tw-grid tw-gap-4 tw-border tw-bg-background tw-shadow-lg" />
+```
+
+It works with `cn`, `cva` and CSS variables.
+
+The cli can now also detect `tailwind.config.ts` and add the TypeScript version of the config for you.
+
+That's it. Happy Holidays.

+title: March 2024 - Introducing Blocks
+description: Ready-made components for dashboards and authentication pages.
+date: 2024-03-22
+---
+
+One of the most requested features since launch has been layouts: admin dashboards with sidebar, marketing page sections, cards and more.
+
+**Today, we're launching [**Blocks**](/blocks)**.
+
+<a href="/blocks">
+  <Image
+    src="/images/dashboard-1.jpg"

+  />
+  <span className="sr-only">View the blocks library</span>
+</a>
+
+Blocks are ready-made components that you can use to build your apps. They are fully responsive, accessible, and composable, meaning they are built using the same principles as the rest of the components in shadcn/ui.
+
+We're starting with dashboard layouts and authentication pages, with plans to add more blocks in the coming weeks.
+
+### Open Source
+
+Blocks are open source. You can find the source on GitHub. Use them in your projects, customize them and contribute back.
+
+<a href="/blocks">
+  <Image

+  />
+  <span className="sr-only">View the blocks library</span>
+</a>
+
+### Request a Block
+
+We're also introducing a "Request a Block" feature. If there's a specific block you'd like to see, simply create a request on GitHub and the community can upvote and build it.
+
+<a href="/blocks">
+  <Image
+    src="/images/dashboard-3.jpg"

+title: August 2024 - npx shadcn init
+description: Complete CLI rewrite with support for all major React frameworks.
+date: 2024-08-31
+---
+
+The new CLI is now available. It's a complete rewrite with a lot of new features and improvements. You can now install components, themes, hooks, utils and more using `npx shadcn add`.
+
+This is a major step towards distributing code that you and your LLMs can access and use.
+
+1. First up, the cli now has support for all major React framework out of the box. Next.js, Remix, Vite and Laravel. And when you init into a new app, we update your existing Tailwind files instead of overriding.
+2. A component now ship its own dependencies. Take the accordion for example, it can define its Tailwind keyframes. When you add it to your project, we'll update your tailwind.config.ts file accordingly.
+3. You can also install remote components using url. `npx shadcn add https://acme.com/registry/navbar.json`.
+4. We have also improve the init command. It does framework detection and can even init a brand new Next.js app in one command. `npx shadcn init`.
+5. We have created a new schema that you can use to ship your own component registry. And since it has support for urls, you can even use it to distribute private components.
+6. And a few more updates like better error handling and monorepo support.
+
+You can try the new cli today.
+
+```bash
+npx shadcn init sidebar-01 login-01
+```
+
+### Update Your Project
+
+To update an existing project to use the new CLI, update your `components.json` file to include import aliases for your **components**, **utils**, **ui**, **lib** and **hooks**.
+
+```json showLineNumbers {7-13} title="components.json"
+{
+  "$schema": "https://ui.shadcn.com/schema.json",
+  "style": "new-york",
+  "tailwind": {
+    // ...

+    "utils": "@/lib/utils",
+    "ui": "@/components/ui",
+    "lib": "@/lib",
+    "hooks": "@/hooks"
+  }
+}
+```
+
+If you're using a different import alias prefix eg `~`, replace `@` with your prefix.
