- Remove scraper health check (port 3008) since dev:browser-use
was removed from dev:start; always report scraper as ready
- Add checkPort helper with localhost fallback for frontend
check to handle Windows IPv6/IPv4 resolution issues
Skip browser/Facebook detection in /setup/status when port 3008
is not reachable, so first_run only depends on env + Ollama.
This prevents the setup wizard from showing endlessly when
browser-use service is not running.
