Browser Automation Rules

Chrome CDP is available at host.docker.internal:9223 (proxy to host Chrome on port 9222)
Always use browserWSEndpoint with URL rewrite (localhost:9222 → host.docker.internal:9223)
Never use browserURL — it resolves to an unreachable localhost address
Never call browser.close() — use browser.disconnect() to release without killing Chrome
Set NODE_PATH=/usr/lib/node_modules if require('puppeteer-core') fails
The Chrome profile is shared — all agents see the same logged-in sessions
