PollDownloadWorker now publishes status/result/error events to both the
EventBus (for live UI updates via SubscribeEvents) and AlbumEventRepository
(for DB persistence and replay on reconnect).
- Add AlbumID, Quality, WorkflowRunID to PollDownloadArgs
- Add EventBus and AlbumEvents fields to PollDownloadWorker
- Publish status events with progress % on each poll tick
- Publish result event on download completion
- Publish error events on torrent failure
- Thread workflowRunID through saveTorrentAndDownload for event correlation
- RecoverOrphanedDownloads populates AlbumID/Quality from download record

- Add internal/musicfs package: gRPC client, TriggerRescan (stream consumer), EnrichFiles (BatchUpdateMetadata), DeriveSubdir helper
- Add MusicFS config section (enabled, endpoint, origin_id, origin_root, timeout)
- Wire MusicFSClient into PollDownloadWorker: on download completion, trigger scoped rescan then push enriched metadata
- Fix album auto-persist in monitor workflow: persist artist+album from metadata-agregator before saving torrent/download
- Add filterByActiveSeeders: skip torrents where magnet resolution found 0 real active seeders
- Add musicfs proto to buf.gen.yaml inputs
- Enricher only sends non-empty fields to avoid overwriting existing file tag data with empty values
