Major client-SDK ergonomics refactor and three independent fixes for UI lag that accumulated under long-running sessions.

​
New

  • cam(id) bound accessor — manager.camera(id) returns a BoundCamera with every API method pre-bound to the camera ID. Callers no longer repeat cameraId on every invocation: 
    const cam = manager.camera(id);
await cam.setProperty("iso", { value: "0x320" });
await cam.afShutter();
  • CameraManager now drives discovery polling with auto-reconnect, autoConnect, and event-driven updates. Replaces the older ad-hoc CameraClient + manual polling pattern.

​
Fixed

  • Poll stacking under idle — setInterval had no in-flight guard, so polls queued after the browser woke and saturated the 6-connection pool. Added isPolling flag in CameraManagerCore.poll().
  • Property-refresh connection exhaustion — refreshProperties fired 12 parallel getProperty GETs; after ~2 minutes all connections were held. Replaced with a single getAllProperties call plus a mutex (isRefreshingRef) against concurrent bursts.
  • Ghost SSE callbacks after reconnect — EventStream.off() removed handlers from an internal map but not from the native EventSource. Added nativeListenerMap so off() reaches both layers.
  • ISO duplicate entries in getAllProperties — SDK returns two ISO rows (one read-only, no values; one writable). Server-side dedup now prefers the entry with values/writable.
