…entCapabilityError The "client returns -32601 when the server requests roots" flow no longer exists under MRTR (servers no longer send standalone server-to-client requests, and an inputRequest for an undeclared client capability is forbidden). And undeclared client capabilities are now signalled by MissingRequiredClientCapabilityError (-32003), not -32601. Rewrite the MethodNotFoundError JSDoc to scope -32601 to unknown methods and unadvertised server capabilities, and point readers at -32003 for the undeclared-client-capability case. Replace the stale roots-not-supported.json example with prompts-not-supported.json.
