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

Dylan M. TaylorandClaude Sonnet 5.5 d94790d97a refactor: replace redundant closures with method paths (SonarCloud S1612) (#1261)
Skipped where the receiver type is generic or not evident without a compiler (wrapping_neg, total_cmp, exists, to_vec, as_ref, split_first, Option::into_inner).

5fadda5ecf chore: resolve SonarCloud maintainability issues (#1255)
* chore: resolve SonarCloud maintainability issues

* fix: address shellcheck SC2059 and fix generic cast ambiguity

* style: apply rustfmt formatting

* fix: restore compile and behaviour in Sonar refactors

- fonts: char::is_alphanumeric takes &self, so filter needs a closure
- h264: keep the mvd accumulator as i32 (prefix is usize)
- model: annotate the non-stacked range accumulators as f64
- engine: chart.options still clears the raw chart XML for upDownBars
  and quartiles; smartart goes back to the glob import (cmd! macro)
- web: keep the original viewport meta (behaviour change)

* Assign positional parameters to locals in sha256 verification

Nikita RakitinandCursor 6b071aa053 Video: check the whole picture store against a memory budget (#398)
Per-axis size caps let AV1 accept 65536x65536 frames (over 8 GiB of luma)
and did not count references or pictures in flight. A shared budget module
in deckcraft-bitstream sizes a picture with checked arithmetic, and the
AV1, VP9, HEVC and H.264 decoders refuse a picture size whose current
picture, reference slots and in-flight pictures would exceed 4 GiB (1 GiB
on 32-bit), before allocating. set_memory_budget lowers it for hosts and tests.

Nikita RakitinandCursor 1fe638bcf8 AV1: reject duplicate film-grain scaling points; a failed job still publishes (#394)
The film-grain header accepted scaling points whose values didn't strictly
increase, and building the scaling lookup then divided by zero. In threaded
decoding the panic left the frame's reference and picture slots unset, so
the output and dependent frames waited forever.

- The header rejects Y/Cb/Cr point values that don't strictly increase
  (spec 6.8.20).
- The scaling lookup moves into scaling_lut, which skips a non-increasing
  pair and uses checked indexing (defence in depth).
- run_job decodes inside guarded (catch_unwind), so a panic becomes an error
  published to the picture and reference slots.

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).
