Root cause: Browser object was bound to a short-lived connect context that expired after Start() returned, causing all subsequent operations to fail instantly with context canceled. Changes: - Use goroutine + channel for connect timeout instead of binding context - Add Microsoft Edge auto-detection as fallback browser - Add isolated user data directory to avoid profile conflicts - Add leakless config option (disabled by default on Windows) - Change WaitStable to WaitLoad for more reliable page loading - Add Windows troubleshooting documentation Tested on Windows 10 Pro with Edge, successfully loads vnexpress.net.
