## Description
This PR addresses the following improvements:
**Unify Prettier Version**: Currently, the Prettier version used in
`/package.json` and `/codex-cli/package.json` are different. In this PR,
we're updating both to use Prettier v3.
- Prettier v3 introduces improved support for JavaScript and TypeScript.
(e.g. the formatting scenario shown in the image below. This is more
aligned with the TypeScript indentation standard).

/>
**Add Prettier Auto-Formatting in lint-staged**: We've added a step to
automatically run prettier --write on JavaScript and TypeScript files as
part of the lint-staged process, before the ESLint checks.
- This will help ensure that all committed code is properly formatted
according to the project's Prettier configuration.
More of a proposal than anything but models seem to struggle with
composing valid patches for `apply_patch` for context matching when
there are unicode look-a-likes involved. This would normalize them.

This PR replaces all hard‑coded patch markers in apply‑patch.ts with the
corresponding constants (now) exported from parse‑apply‑patch.ts.
Changes
• Import PATCH_PREFIX, PATCH_SUFFIX, ADD_FILE_PREFIX,
DELETE_FILE_PREFIX, UPDATE_FILE_PREFIX, MOVE_FILE_TO_PREFIX,
END_OF_FILE_PREFIX, and HUNK_ADD_LINE_PREFIX from parse‑apply‑patch.ts.
• Remove duplicate string literals for patch markers in apply‑patch.ts.
• Changed is_done() to trim the input to account for the slight
difference between the variables.
Why
• DRY & Consistency: Ensures a single source of truth for patch
prefixes.
• Maintainability: Simplifies future updates to prefix values by
centralizing them.
• Readability: Makes the code more declarative and self‑documenting.
All tests are passing, lint and format was ran.
