- _download_phase_from_status now falls back to checking requested_formats
when top-level vcodec/acodec are both 'none' (common when yt-dlp uses
separate downloaders for video+audio streams)
- Clear download_phase on download completion/error (was persisting stale
phase value in finished state)
- Add debug logging in put_status for phase detection
- Update docker-compose.local.yml to match docker-compose.yml structure
with local image build (adds TARGETARCH build arg)
