Struct DevToolsOutputWatcher 

pub struct DevToolsOutputWatcher { /* private fields */ }

Collects a browser’s stderr so the launcher can confirm which process owns the debugging port.

Register listener with the process before it starts; the process output keeps being drained after startup so a chatty browser never blocks on a full pipe.
