Code Review
This pull request introduces a new --enable-draft-specs CLI flag to allow users to opt-in and test upcoming draft MCP specifications, updating the server configuration, documentation, and message processing logic accordingly. It also removes the unused VerifyProtocolVersion function. The reviewer noted that if a client proposes the draft version while draft specs are disabled, the server currently fails initialization rather than negotiating down to the latest supported stable version, and suggested a fix to handle this gracefully.
