Added Protocol::connect_tls() method using rustls::StreamOwned<rustls::ClientConnection, TcpStream>.
Created AllowAnyVerifier implementing rustls::client::danger::ServerCertVerifier to accept any certificate
AddedClient::connect_tls() that loads ca-certificates.crt if present otherwise falls back to system certs
TLS now works for HTTP1_1 and HTTP2_0 protocols
New DNSCache struct with Arc<Mutex<HashMap<String, DNSCacheEntry»> thread-safe, TTL-based
DNSCacheEntry stores resolved SocketAddr list + expiry timestamp
resolve_dns() now uses trust_dns_resolver::Resolver::from_system_conf() for proper DNS lookups, with fallback to ToSocketAddrs
parse_url() extracts the host, port, and TLS flag from http:// or https:// URLs
Handles explicit ports (example.com:8080) and defaults (80/443)
connect_to() now calls resolve_and_connect() which uses DNS cache + TLS decision logic
Client now tracks redirect_count
send_request() detects 3xx status codes, reads location header, and follows redirects
HTMLTag -enum of all standard HTML5 tags
HTMLAttribute -name/value pairs
HTMLNode - tag + attributes + children + optional text content
HTMLDocument -doctype + root node
HTMLTag::from_string() - case-insensitive parser for all tags
