Subject: [PATCH] Fix WebSocket event type imports in agent-server-client

The isomorphic-ws package doesn't export MessageEvent, CloseEvent, or
ErrorEvent types. These types are defined in the WebSocket namespace
via @types/ws. Updated to use the namespaced types (WebSocket.MessageEvent,
WebSocket.CloseEvent, WebSocket.ErrorEvent) instead of trying to import
them directly from isomorphic-ws.

This resolves TypeScript compilation errors:
- TS2305: Module '"isomorphic-ws"' has no exported member 'MessageEvent'
- TS2305: Module '"isomorphic-ws"' has no exported member 'CloseEvent'
- TS2305: Module '"isomorphic-ws"' has no exported member 'ErrorEvent'
