feat: REST + WebSocket transport adapter

[HexaField]

Summary

Adds the bridge adapter for the feat/sse-to-websocket branch of coasys/ad4m.

Transport: REST + WebSocket RPC

• Patches RestClient.call() to intercept all HTTP requests
• Intercepts WebSocket RPC frames (_ensureWs() pattern) for real-time operation tracking
• Maps REST operations to OperationRecord with transport: 'rest'
• Maps WS RPC calls to OperationRecord with transport: 'ws'
• Tracks SSE/EventSource subscriptions and reconnection events

Integration

In Ad4mClient constructor (REST-based):

import { initDevToolsBridge } from '@ad4m-devtools/bridge';
// After constructing RestClient:
initDevToolsBridge(this);

Builds

• packages/bridge: ✅ tsc clean
• packages/extension: ✅ vite build clean
