BrianHotoppandClaude Opus 4.6 d765ba263a [2.x] fix: Return JSON-RPC error for unknown server methods (#9002) ...

The fallback ServerHandler silently dropped requests with unknown
methods, violating the JSON-RPC spec. Clients like Metals that send
unrecognized requests would never receive a response, potentially
causing timeouts or hangs.

Return a -32601 (Method not found) error response instead.
