Skyler Lehmkuhl ce151ffd61 Pack video into .beam and stream frames + audio from the blob
Video was the only media type always kept external (VideoClip.file_path),
so a project with video wasn't self-contained. Now video packs into the
SQLite container under the same large-media policy as audio (pack < 2 GB
unless the user chose Reference), and both the frames and the embedded audio
track decode by streaming directly from the blob — no temp files.

- New crate ffmpeg-blob-io: an AVIOContext-over-Read+Seek shim (BlobInput)
  that lets ffmpeg demux from an arbitrary byte source. Isolates all the
  unsafe FFI + ffmpeg ABI coupling (version-pinned =8.0.0/=8.0.1). Manual
  Drop teardown order; AVSEEK_SIZE restores the read position (FFmpeg assumes
  a size query doesn't move it — required for MP4 moov-at-end).
- Schema/save/load: VideoClip.media_id; save_beam packs/references video as
  MediaKind::Video (keyed by clip id); load resolves packed vs referenced and
  reports missing sources. A packed clip points its linked video-audio pool
  entry's media_id at the video row so the audio streams from the same blob.
- Frames: video.rs VideoSource{Path,Packed} threaded through new/seek/scan/
  probe/thumbnails (a fresh BlobReader per open); editor builds the source
  from current_file_path (now set before register_loaded_videos).
- Audio: VideoAudioReader::open_source via BlobInput; the disk_reader
  StreamSource block on packed video-audio is removed; the engine's existing
  factory activation routes it unchanged.

Tests: ffmpeg-blob-io AVIO unit tests (WAV via Cursor, seek, open/drop loop);
core packed_video_stream (blob->AVIO->Input) and beam_archive video round-trip;
daw-backend open_source test (compiles; links/runs only off-container).
Runtime-verified: a packed video plays frames + audio after the source file
is removed.
