   * Verifies end-to-end PAC proxy resolution:
   *
   * - The PAC file routes /proxied paths to the local test proxy (port 18888).
   * - The local test proxy injects `x-proxied: test-proxy` into every response.
   * - /direct paths are returned DIRECT — no proxy header added.
   *
   * Both assertions live inside the collection's `tests {}` blocks, so
   * validateRunnerResults confirms the full flow passed.
