e983e3f79f Block IPv6 SSRF bypass via ipv4_compat addresses (#153) 
Adds ipv4_mapped? and ipv4_compat? checks to PrivateNetworkGuard.private_ip?
to block SSRF bypass attempts using IPv6 address formats like:
- ::ffff:169.254.169.254 (IPv4-mapped)
- ::169.254.169.254 (IPv4-compatible)

These formats could previously bypass the link_local? check since Ruby
treats them as IPv6 addresses, not IPv4.
