Use Cloudflare trace by default and validate IPs

Browse Source 
Default IPv4 provider is now CloudflareTrace.
Primary uses api.cloudflare.com; fallbacks are literal IPs.
Build per-family HTTP clients by binding to 0.0.0.0/[::] so the trace
endpoint observes the requested address family. Add validate_detected_ip
to reject wrong-family or non-global addresses (loopback, link-local,
private, documentation ranges, etc). Update tests and legacy updater
URLs.
Default to Cloudflare trace and validate IPs

Use api.cloudflare.com as the primary trace endpoint (fallbacks
remain literal IPs) to avoid WARP/Zero Trust interception. Build
IP-family-specific HTTP clients by binding to the unspecified
address so the trace endpoint sees the correct family. Add
validate_detected_ip to reject non-global or wrong-family addresses
and expand tests. Bump crate version and tempfile dev-dependency.
