The CDP bridge server (ws://localhost:9223 + http://localhost:9224) was never starting because the entrypoint loader instantiates BrowserTool directly, bypassing the package-level register_tools() which called start_cdp_bridge(). Now BrowserTool.__init__() auto-starts the bridge when backend is not "playwright", ensuring the browser extension can connect and be used as the preferred backend over headless Playwright.
