• fix RFD
• Migrate to typescript + bun
• FormInputs
• Navigating
• tests for all

Add test cases for each of these.
Adds typescript support for the interpreter.
Unifies binary protocol with its base host

This should clean up our interpreter code and fix a number of longstanding issues around eventhandling across the boundary.

We still don't have a great solution for liveview.

Wry let's us intercept navigations now, too, which should make accidental navigates impossible.

Going to leave synchronous events for a separate PR as it will need to touch core for event dispatching through the runtime.
