* 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
