Skyler Lehmkuhl c784816615 Phase 2: bound video frame cache + stream the export mux
- VideoManager.frame_cache: unbounded HashMap (grew per distinct frame during
  playback) -> LruCache evicted by a 256MB byte budget. Byte-budget rather than
  frame count is robust across resolutions (a 4K frame is ~33MB vs ~2MB at
  800x600). unload_video pops per-clip keys (LruCache has no retain).
- mux_video_and_audio: stream-merge the two inputs by PTS with one pending
  packet per stream (O(1) memory) instead of collecting every packet into Vecs
  first (O(duration)). Output is byte-identical.
- export AAC: sanitize the planar-f32 path (non-finite -> 0, finite clamped to
  [-1,1]) like the integer paths, with a one-time warning. A stray NaN/Inf
  render sample no longer fails the whole export.
