Introduce internal/safeclient package that DNS-resolves hostnames before connecting and rejects IPs in private/reserved CIDR ranges (loopback, RFC 1918, link-local, cloud metadata endpoints). Replace all direct http.Client.Get calls in scraper.go and rss.go with safeclient.SafeGet. Add 8 new unit tests for the safeclient package. Update existing test files with TestMain hooks for httptest.NewServer compatibility.
