A terminal can produce an open-ended stream of input: keys today, but also resize, paste, mouse, and application-defined events. Bombshell needs a generic boundary for sending those external events into the middleware tree without hard-coding every event category into the UI loop. That boundary should also prevent an exception in installed dispatch middleware from tearing down the terminal session without giving the application a chance to respond.

This API intentionally represents events entering the tree, as distinct from semantic events that elements will later emit to their consumers. It also avoids a universal “handled” protocol, allowing specialized middleware to define its own delegation behavior while dispatch itself reports only success or failure.

This PR adds the middleware-extensible DispatchApi and installs a Host-level error boundary with useDispatch(). Dispatch returns a small success/failure result and preserves the original thrown reason for callers.
