POST /tracks/{id}/optimize enqueues a transcode; GET /stream/{id}?quality=
serves a cached Opus rendition (miss → master + background warm); GET
/stream/{id}/hls/{playlist.m3u8,segment} serves the worker-generated HLS
rendition (AAC-in-TS), with ?token= propagated onto segment URLs for players
that can't set headers. Hexagonal: Transcoder port, FfmpegTranscoder adapter,
TranscodeService + cache-path helpers, transcode_track worker (idempotent),
schemas + deps wiring. ffmpeg already in the image.
