This PR adds a new connection mode called
--auto-connect. To activate it, add the--auto-connectflag to the chrome-devtools-mcp server configuration. With this, chrome-devtools-mcp will automatically connect to the running Chrome instance by looking up the port and the URL in the user data dir for the specified--channel(by default,stable). Requires Chrome M145.
