Exec-Server JSON-RPC Base Sketch

This is a review-only sketch of the simplified exec-server JSON-RPC base.

It is intentionally scoped to the transport and dispatch shape:

• websocket-only transport
• direct JSONRPCMessage -> handler -> JSONRPCMessage processing
• no "jsonrpc": "2.0" envelope requirement
• a local bypass path represented by direct handler calls rather than an in-memory transport

It does not include the later process/* or filesystem RPC surface.

The goal of this sketch is to show the app-server-like structure without stacking the rest of the exec-server implementation on top of it.
