Reject invalid index products and unsafe paths, cap encoded/decoded residency, recover allocation and partial worker-start failures, release GL movie textures with their context, and serialize diagnostics through the presenter. Real SDL decode/restart/failure test passes and SDL2 C seam compiles warning-free. Guest/present timestamp ownership remains a separate design gate. Tracking: beads-eio.3.388.

/* gpu_fmv_hd -- high-definition replacement of FMV movies (24-bit MDEC frames).
|
|
*
|
|
* A pack (<exe>/fmv_hd, or PSX_FMV_HD_DIR) holds one folder per movie:
|
|
* index.bin a FmvHdIndexHeader, then for every source frame a sig_w x sig_h
|
|
* luminance signature (u8, the mean of each cell of the original frame);
|
|
* frames/NNNNNN.jpg HD frames, `sub` per source frame (interpolation), numbered
|
|
* source_index * sub + k.
|
|
* Every presented 24-bit frame's signature is matched against the pack (a local search
|
|
* around the last recognised frame, then a global one); the matching HD frame, decoded
|
|
* ahead by worker threads, is presented instead. Audio, timing and control (skipping the
|
|
* movie) stay the game's own. No pack: no effect.
