"""rpc.py — JSON-RPC 2.0 dispatcher with method registry.

The dispatcher is intentionally minimal: validate envelope, look up method,
call it with (params, ctx), shape result into a JSON-RPC response.

Application errors (e.g. NotOriginator) get HTTP 403 at the handler level;
the dispatcher just signals the kind via raised exceptions.
