feature: Phase 18.1 — derive Opus 320 + seek-index sidecar at ingest

Background-job transcode (ffmpeg/libopus) after source store; pure C# Ogg walker builds the 0.5s-bucketed granule→byte seek index + captures the OpusHead/OpusTags setup header into a per-track sidecar in a new track-opus vault. Best-effort, additive, regenerated on replace-audio.
