Adds a live progress channel for the library index:
- indexer.ts: progress subscribers (onIndexProgress) + throttled emit during the
walk, and buildReport() for a final summary.
- sidecar: GET /reindex/stream (SSE) — triggers a build if idle (?trigger=0 to
watch only), streams `progress` events, ends with a `done` event carrying the
report; auto-proxied at /api/music/reindex/stream for the app. Sidecar also
writes DATA_PATH/music/.server (its port) for local tooling.
- scripts/reindex-music.ts: CLI that reads the port file, follows the SSE, prints
live progress + a final report. Run: bun scripts/reindex-music.ts
