* fix(tools): default-deny non-global IPs in SSRF check is_blocked_ip used hand-written denylists that missed CGNAT (100.64.0.0/10, incl. Alibaba metadata 100.100.100.200), 198.18.0.0/15, Azure WireServer (168.63.129.16), and IPv6 forms wrapping private IPv4 (NAT64, 6to4). Block anything that is not is_global, keep explicit entries for ranges is_global may allow or that vary by Python version, and unwrap IPv4-mapped and NAT64 (64:ff9b::/96) addresses so the embedded IPv4 is checked. 6to4, Teredo and local-use NAT64 are non-global and blocked.

Add them, Teredo, IPv4-compatible (::/96), IPv4-translated (::ffff:0:0:0/96) and deprecated site-local (fec0::/10) to the explicit IPv6 list, which also closes forms is_global allows on every version.
