Sid 652f3cc3fe feat: basic annotation syntax support for lang (#7609)
* chore: basic annotation support

* chore: string and escape cases

* feat: add basic multiline support

* fix: simplify dedentation logic in annotation multiline text block

* chore: fix asserts

* feat: add annotation support to env and collection

* feat: enhance annotation parsing with support for quoted arguments and nested parentheses

* refactor: feedback, remove inline annotations

* feat: move serializeAnnotations function to utils and update imports
