Refresh Stale DNS Records on 1.1.1.1

Introduced a tool to purge individual DNS records from the 1.1.1.1 DNS resolver's cache. This allows domain owners to force an update of cached DNS entries, reducing the propagation delay from the default TTL (up to 3 hours) to a few seconds. The tool supports purging A, AAAA, CNAME, DNSKEY, DS, MX, NAPTR, NS, PTR, SPF, SRV, SSHFP, TLSA, and TXT record types.
