- 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
