Package activity persists bus lifecycle events into the torrent_events table so the Activity page can render a full history (across restarts) instead of just the in-memory live stream.

Package renamer applies naming format templates to produce filesystem-safe filenames for downloaded media files.

Package torrent owns the anacrolix/torrent client lifecycle and the Session type that exposes it to the rest of haul.

Package admin owns the diagnostic registry and the soft-delete shim (cleanup_history) used by the Settings → System → Diagnostics tab.
