- Remove all output by default to prevent workflow interruption
- Queue changes silently to .doc-guardian-queue
- Add file+type deduplication (same file won't be queued twice)
- Add DOC_GUARDIAN_VERBOSE=1 env var for opt-in notifications
- Users run /doc-sync or /doc-audit to process queue
Fixes#312 (partial - addresses issues 1, 2, 3)
