+Test Suite: can_process_url URL validation for deep crawl strategies
+
+Covers:
+1. Single-label (dot-less) hostnames such as intranet hosts, localhost and
+   Docker service names are accepted for http(s) URLs.
+2. Regular hostnames, IP literals and ports keep working.
+3. URLs without a scheme/netloc and non-http(s) schemes are still rejected.
+4. The filter chain still applies for depth > 0, while depth 0 bypasses it.
