Pin firefox-12: cross-OS render parity + always-present standard fonts
- BINARY_VERSION -> firefox-12 (self-calibrating font widths, per-family canvas distinctness, render-noise that preserves solid reference renders). - font_pool: the standard Windows fonts (Calibri, Franklin Gothic, Gadugi, Javanese Text, Myanmar Text) move from the per-profile optional set to core, so they are always present and the detected font set matches a real Windows install on every host. Defensive dedup in derive_font_prefs. - GPU persona applied on every platform (Linux/macOS present a coherent Windows GPU + WebGL params); pool re-rooted on a real-device GPU mix; render seeds recalibrated. - prefs: emit absolute per-family font widths that the binary self-calibrates. - geoip: always pull the latest mmdb via the releases/latest permalink, checked each launch, offline-safe (no pinned tag that can 404). - tests: per-font canvas distinctness, solid-readback purity under render-noise, always-present standard-font invariant, no duplicate families.

daijro/geoip-all-in-one rebuilds weekly and keeps only the latest ~2 releases,

so `ensure_geoip_mmdb` never pins a tag: on every call it resolves the CURRENT

latest tag (from the `releases/latest/download` permalink, no GitHub API) and
|

downloads it only when it differs from the cache. These tests mock the cache
|

root, the tag resolver, and the per-tag download so nothing touches the network.
