Second-pass logging cleanup: consistent [LEVEL] [module] format across all 41 files. Remove stale prefixes ([CF], [SYNC], [SCHED], [API], [STORAGE], [HEALTH], [ROLLBACK]). Remove 5 duplicate log lines. Gate ungated DEBUG lines. Fix wrong log levels (restore start WARN→INFO). Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
