Affaan Mustafa e7b5c62eb7 fix: use readFile utility in hooks and add pattern type safety
- Replace raw fs.readFileSync with readFile() from utils in
  check-console-log.js and post-edit-console-warn.js to eliminate
  TOCTOU race conditions (file deleted between existsSync and read)
- Remove redundant existsSync in post-edit-format.js (exec already
  handles missing files via its catch block)
- Resolve path upfront in post-edit-typecheck.js before tsconfig walk
- Add type guard in getGitModifiedFiles() to skip non-string and
  empty patterns before regex compilation
