IAsyncBridgeTransport interface

A host that can acknowledge state delivery before the next dependent frame is sent.

Remarks

Desktop implements this because its IBridgeTransport.Publish coalesces snapshots per route, and awaiting script completion lets a slow WebView fall behind into a bounded recovery snapshot. CS-WebUI does not implement it: WebUI's only acknowledged script call answers from one client and blocks a native thread. Its IBridgeTransport.Publish instead writes to every client synchronously, under WebUI's process-wide send lock, and blocks until each socket write completes or times out. A slow client therefore applies TCP-level back-pressure: the blocked write holds the bridge's delivery queue, which falls back to a recovery snapshot once it is full, and it also delays sends to every other CS-WebUI window. This is not application-level acknowledgement; frames are written in order, not confirmed as applied.
