Dylan M. Taylor d4945d0443 fix(codecs): harden media decoders against resource amplification and unbound state (#1285) 
* fix(codecs): harden media decoders against resource amplification and unbound state

- Ogg recovery (Finding 29): Reuse capture search window buffer and bound
  cumulative recovery work to prevent quadratic re-scanning.
- Opus packet concealment (Finding 40): Skip empty stored Opus packets
  instead of triggering packet-loss concealment audio.
- Opus decoded PCM budget (Finding 63): Enforce aggregate MAX_PCM_SAMPLES
  limit before expanding planar audio samples.
- H.264 DPB reference eviction (Finding 56): Validate MMCO 6 against
  max_long_term_frame_idx and evict oldest entries when capacity is reached.
- HEVC missing reference frames (Finding 57): Share gray replacement frames
  and bound missing references to DPB buffering limits.
- AV1 show_existing_frame budget (Finding 69): Cap frame outputs per chunk
  to 32 to prevent output batch memory explosion.
- AV1 nonuniform tile bounds (Finding 89): Enforce MAX_TILE_COLS and
  MAX_TILE_ROWS limits on nonuniform tile layouts.

* fix(codecs): refine show_existing_frame limit, PCM capacity check, and buffered Ogg search

Nikita 6873a25635 Codecs: a hostile number is a format error, not an overflow 
H.264 and HEVC quantiser offsets, Matroska block times, Opus granule timing and QuickTime PCM frame sizes are range-checked before the arithmetic.

Brandon ThomasandClaude Opus 5.5 4375fe7b89 Media playback: slidecraft-media (probe, audio decode, H.264/HEVC/VP9/AV1 video, mixer and clock), cpal output, editor control bar, slide show playback, media.* commands 
- crates/media: probe (duration, rate/channels, size/fps; WMA/WMV recognised), audio decode to
  f32 PCM (MP3, AAC M4A/ADTS, ALAC, WAV, AIFF, CAF, FLAC, Vorbis via symphonia; Opus with our
  decoder in Ogg/WebM/MKV), video decode (MP4/MOV/WebM/MKV) with YUV->RGBA, poster frames,
  trim/fade/volume, Player mixer + per-voice clock (device-clocked or wall-clocked), VideoFeed.
- Codec crates ported from FilmCraft: bitstream, h264, hevc, vp9, av1, isobmff, matroska, ogg, opus.
- insert.audio/insert.video probe and store duration/size and a poster frame; unplayable media
  is embedded with a warning. New media.play/pause/toggle/stop/seek/info/posterFrame.
- UI: MediaHost (cpal output injected by the desktop app), control bar under media, video frames
  on canvas and in the show; autoplay, click to play, loop, rewind, across slides, hide, full screen.
- Tests with in-code WAV/AIFF and CC0 self-generated fixtures (make.sh, ATTRIBUTION.md rows).
