IP address validation
Classify an IP address string. Return "ipv4" if it is a valid IPv4 address, "ipv6" if it is a valid IPv6 address, and "invalid" otherwise. Strict validation applies: IPv4 octets must be 0-255 with no leading zeros, and IPv6 must follow standard hextet/:: rules.

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
