fix: use separate user-data-dir for CDP browser to avoid conflicts with existing instances

Browse Source 
When Edge/Chrome is already running, a new instance with --remote-debugging-port
joins the existing process instead of starting CDP. Using a dedicated profile dir
forces a separate process. Also retry CDP port check up to 6 seconds.
