Registry change feed stream

Changed on

Subscribe to registry feed pages over Server-Sent Events. This is a push-friendly transport for the same cursor contract as /api/registry/feed: clients still persist cursor, apply only feed events, and recover from cursor_expired by re-bootstrapping. The stream emits feed events containing a full feed page, heartbeat events while caught up, and error before closing when the cursor expires or the server cannot query the feed.
