StdioServerTransportProvider only reported MCP_2024_11_05 as its supported protocol version. Since the stdio transport is unchanged across all protocol versions, it should advertise support for all of them so version negotiation works correctly with newer clients. Without this fix, a client requesting 2025-06-18 or later would receive 2024-11-05 as the server's highest supported version, potentially causing a version mismatch.

StdioServerTransportProvider.protocolVersions()only reportedMCP_2024_11_05, causing version negotiation to fail with newer clients.
