gsxdsm 64cb17c100 FN-9204: advertise a valid memory MCP server version ...

Make the built-in memory MCP server complete the SDK-validated initialize handshake.

- Include a non-empty version in fusion-memory serverInfo responses.
- Cover the real SDK handshake, malformed-response skip path, and JSON-RPC envelopes.
- Document the protocol requirement and add a patch changeset.
