Miguel Ángel d2d9c169fb feat(producer): add audio-only render endpoint for parallel chunk stitch
Adds POST /render/audio that compiles the composition to discover audio
elements, then processes only the audio tracks via processCompositionAudio
without capturing any video frames. Returns the mixed audio file path.

This eliminates the stitch bottleneck in parallel chunk rendering where
the full composition was re-rendered just to extract the audio track
(104s → ~5-10s for a typical composition).
