Dylan M. Taylorandjayzed80 227cfee7e0 craft-video: DeckCraft decoder fixes (HEVC queued-output budget, VP9 failed superframes, AV1 tile metadata cap, H.264 POC overflow) (#1010 )

* craft-video: budget HEVC queued output, drop a failed VP9 superframe's repeats, serial AV1 tiles past a metadata cap

Ported from storytold/deckcraft#1778 and #1841, which landed in DeckCraft's
decoder copies after craft-video took them.

* craft-video: H.264 picture order count no longer overflows on extreme stream values

Wrapping arithmetic through the POC type 0/1/2 paths, frame_num_offset and
the MMCO5 prev_ref_lsb update. Ported from storytold/deckcraft#1913.

craft-video

Clean-room pure-Rust video codecs for the Craft apps, one feature per codec: DNxHD/DNxHR, VP8, ProRes and H.264.

Input and output are byte slices and planar sample buffers; the crate opens no files itself and performs no filesystem I/O.
Implemented from published standards and RFCs (SMPTE ST 2019-1, RFC 6386, SMPTE RDD 36 and ITU-T H.264).
Tested against ffmpeg as an external oracle with roundtrips, hostile fuzzing, and conformance vectors. No unsafe, no panics on corrupt streams. Builds for wasm32-unknown-unknown.
Containers (MP4/MOV, Matroska/WebM), bit-level I/O (craft_media::bitstream) and shared identifiers (CodecId, CodecParams) come from craft-media.
