- `frontComponentHostCommunicationApi` gets a new object reference on
every render, causing the `useMemo`/`useEffect` in
`FrontComponentWorkerEffect` to tear down and re-create the web worker
each time.
- Decouple the host API lifecycle from the worker lifecycle by moving
thread.exports updates into a dedicated
`FrontComponentUpdateHostCommunicationApiEffect` that mutates the
thread's exports object in place via Object.assign.
- Rename `FrontComponentHostCommunicationApiEffect` to
`FrontComponentInitializeHostCommunicationApiEffect` for clarity.
