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.
