Remote Control session setup now threads through a new callback for cancelling a queued message

What

The setup code for Remote Control bridge sessions (used to connect Claude Code to remote clients like a mobile app) now accepts and passes along a new onCancelAsyncMessage callback, alongside its existing handlers for things like interrupting or stopping a task.

Why

This is plumbing to support cancelling a specific queued message from a remote client mid-session, rather than only being able to interrupt an entire turn.
