feat(core-ide): add MCP bridge (SERVER) and Claude bridge (CLIENT)
SERVER bridge (mcp_bridge.go):
- HTTP server on :9877 exposing 24 MCP tools
- Window management: list, get, position, size, bounds, maximize,
minimize, restore, focus, visibility, title, fullscreen, create, close
- Webview: eval JS, navigate, list
- System: clipboard read/write, tray control
- Endpoints: /mcp, /mcp/tools, /mcp/call, /health, /ws, /claude
CLIENT bridge (claude_bridge.go):
- WebSocket relay between GUI clients and MCP core on :9876
- Auto-reconnect with backoff
- Bidirectional message forwarding (claude_message type)
Moved HTTP server from IDEService to MCPBridge for unified endpoint.
