stageMs (hash, session boot, capture, encode) and the worker-summed seek, before-capture and
screenshot ms, so one run shows which step of a frame costs most.
* fix(engine): h265 renders no longer fail on hosts with more than 16 cores
libx265 rejects more than 16 frame threads, so the thread count taken from the
CPU quota is now capped at 16 for x265. x264 is unchanged.
* fix(engine): pass the encoder to the thread cap in the CFR re-encode
* fix(core): release decoded preview audio once no clip uses its source
The preview transport cached every decoded audio buffer by source until the player was destroyed. Each scheduling pass now drops cached buffers whose source no clip in the document still uses (scene edits, swapped sources), and keeps the rest so playback never re-decodes a clip still in the film.
* fix(core): drop the comment the comment-share ratchet rejects
* perf(producer): the audio task probes each video for sound instead of extracting its frames
* test(producer): the audio task finds a video's sound from a probe, with no frames extracted
* perf(engine): the audio mix reads clips held at a URL many at a time
* style(engine): format the remote clip slot choice
* fix(producer): the audio task places a video's sound in the window extraction would give it
* style(producer): format the slot cases of the script-src audio test
* fix(studio-server): project history no longer copies video, audio or huge files
* fix(studio-server): clean drops old video and audio copies in every history
* fix(studio-server): TypeScript source is not media, so its history is kept
* fix(studio-server): split the media reclaim and point the slow-copy route test at a non-media file
* fix(studio-server): no unused expression when collecting a history's hashes
* fix(cli): capture images declared only through srcset
* chore: prepare conflict resolution against current main
* fix(capture): retain srcset coverage with validated GIF redirects
* fix(cli): close asset streams when clients disconnect
* chore: prepare conflict resolution against current main
* fix(cli): retain asset disconnect cleanup with current main
* fix(cli): honor HTML attribute casing in frame-rate defaults
* chore: prepare conflict resolution against current main
* fix(cli): preserve HTML fps casing with shared cloud defaults
* fix(core): preserve literal percent in beat source paths
* chore: prepare conflict resolution against current main
* fix(core): retain beat path handling with current main
