            This PR updates the fastmcp.json schema files to match the current source code.

            The schema is automatically generated from `src/fastmcp/utilities/mcp_server_config/` to ensure consistency.

            **Note:** This PR is fully automated and will update itself with any subsequent changes to the schema, or close automatically if the schema becomes up-to-date through other means. Feel free to leave it open until you're ready to merge.
