- Added getMultiRepoJSONLPaths() helper to enumerate all JSONL files
- Updated daemon_sync.go to capture/update snapshots for each repo
- Added TestMultiRepoDeletionTracking to verify fix
- Added TestMultiRepoSnapshotIsolation for isolation guarantees
Previously, deletion tracking only worked for single-repo mode because
snapshot operations were hardcoded to the primary JSONL path. This fix
ensures snapshots are managed per-repository in multi-repo mode.
