Support MCP spec 2026-07-28 end to end. The MCP client negotiates the protocol era automatically (`server/discover` probe with legacy fallback), so integrations hosted on modern-only MCP servers connect without the server enabling legacy compatibility. Executor-hosted MCP endpoints serve both eras, and the `executor mcp` stdio bridge passes either era through to the daemon.
