Use --log-level log for fmt-check to preserve file list

Codex feedback: --log-level warn suppresses the file list when prettier
--check fails, making it impossible to know which files need formatting.

--log-level log:
- Shows failing file paths when issues are found
- Suppresses verbose (unchanged) messages for clean files
- Maintains clean output in success case
