#1198 dde826e Thanks @threepointone! - Derive callbackHost from connection.uri in addMcpServer when called from a @callable method over WebSocket. Previously, callbackHost had to be passed explicitly (or read from an env var) because the WebSocket onMessage context has no HTTP request to derive the host from. Now the host is automatically extracted from the WebSocket connection's original upgrade URL, so addMcpServer("name", url) works without any extra options in callables. Also adds vite/client to the shared agents/tsconfig types for TS6 compatibility with CSS side-effect imports.
