1. 10s timeout for CDP init commands — frozen or hibernated tabs (common in Ghost Browser and other Chromium forks) no longer block the entire Playwright connection setup. Init commands like Page.enable, Runtime.enable, and Network.enable time out individually after 10 seconds.
2. Multi-profile relay routing — extension connections are identified by per-profile install id, so two Chrome profiles signed into the same Google account no longer replace each other.
3. Better browser name detection — shows more specific browser names using full user-agent client hints.
