Wraps the three additional entry points where user server code runs
outside fetchHandler's own context wrap:
- the server-function RPC path (/__wrnexus/rpc) intercepted before
handlers.fetch in the dev server (index.ts) - what server.fn() travels
- the service RPC path (isRpcPath) inside fetchHandler, which runs
implement()/implementStream() service code before ctx existed
- the HMR-sync handler, which runs real load blocks/actions via dispatch()
