feat(serve): add remote browser control over TCP with token auth

Exposes a local browser over a TCP socket so remote machines can
  control it using the same CLI and Python API. Token auth (auto-generated
  via secrets.token_urlsafe) is on by default; --no-auth disables it.
  Profile routing via _route message field lets clients target specific
  browser instances on the remote host. BROWSER_CLI_PROFILE is forwarded
  automatically so --browser flag works transparently over remote.
  - browser-cli serve [--host] [--port] [--token] [--no-auth]
  - browser-cli --remote HOST:PORT --token TOKEN <command>
  - BrowserCLI(remote="host:port", token="...").tabs_list()
