* perf(engine): one-pass SDR-to-HDR extraction with cache-key transform Mixed-HDR compositions converted each SDR source with a full libx264 re-encode (convertSdrToHdr) before extraction. The BT.709 to BT.2020 colorspace remap now runs as a filter inside the extraction pass itself; convertSdrToHdr and the _hdr_normalized intermediate are deleted. Same shape as the earlier one-pass VFR change. Also fixes a cache-poisoning bug this exposed: the HDR preflight rewrote entry.videoPath AFTER the cache-key snapshot, so a mixed-HDR render cached converted frames under the plain source key and a later SDR render of the same trim would have served HDR-tinted frames. The cache key now carries an optional transform discriminator; keys without a transform stay byte-compatible with existing entries. * fix(engine): attribute SDR-to-HDR extract failures, pin filter-order intent Review hardening for one-pass SDR-to-HDR: - ffmpeg failures now carry an 'SDR→HDR conversion failed (colorspace filter in extract pass)' prefix when the remap is in the chain, so a filter-less ffmpeg build fails loudly with attribution instead of a generic extract error. - Comments pin the fps-before-colorspace ordering intent and mark sdrToHdrTransfers as the canonical read for both the cache key and extraction options. - Cross-render cache-poisoning regression test now compares frame BYTES across the cache boundary: mixed-HDR render then plain-SDR render of the same trim must produce different pixels, and a repeat plain render must hit the plain entry with byte-identical frames.
