While a recorder is running, the capture container tees an HLS
stream into /live/<assetId>/ alongside the ProRes master upload.
The asset row is pre-created at recorder start with status='live'
so the clip appears in the library immediately. /api/v1/assets/:id/stream
returns the HLS playlist URL until recording stops, then proxy.
* docker-compose: shared wild-dragon-live mount on api/capture/web-ui
* migration 001-add-live-status: idempotent ALTER TYPE for asset_status
* mam-api: runMigrations() on boot; recorders.js pre-creates live asset
+ passes ASSET_ID; assets.js POST upserts on existing live row instead
of inserting a duplicate, and stream route returns HLS for live assets
* capture: parallel HLS ffmpeg into /live/<assetId>/; ASSET_ID env
* web-ui: nginx serves /live/, preview.js loads hls.js, LIVE badge added
