Servers (170 total, was 104):

ipv64.net Primary + Secondary (Hetzner DE, DoH + DoT)
64 ISP DNS entries across 14 countries: DE / AT / CH / NL / FR / GB / US / CA / AU / JP / CN / RU / BR / IN
New isp tag; ISP group starts collapsed in GUI

CLI:

IPv6 results showing IPv4 address: core.py now reads server["ip"] (the address chosen by the AF picker) before falling back to ip4/ip6. IPv6 test results now show the correct IPv6 2xxx::… address.
Server selection counting too many: Servers in multiple groups (e.g. Cloudflare in Recommended + Privacy) now share a single BooleanVar. Unchecking in any group correctly excludes the server.
Group header checkbox: Each category header now has a checkbox that checks/unchecks all servers in that group.
