🌍 Automatic Proxy GeoIP -> Timezone, `Intl.DateTimeFormat`, Geolocation & `Accept-Language` Synchronization

TZ
tz_geo_sync OP / ELITE MEMBER
Before launching a browser instance on a rotating residential proxy, query the proxy exit IP against a local `GeoLite2-City.mmdb` file (<0.5ms) and automatically set CDP `Emulation.setTimezoneOverride`, `Emulation.setLocaleOverride`, and `Emulation.setGeolocationOverride` to match the exact city coordinates and IANA timezone (`America/Chicago`, `Europe/Berlin`, etc.).

Also check `new Date().getTimezoneOffset()` vs `Intl.DateTimeFormat().resolvedOptions().timeZone`—both must match the proxy IP's state/country including Daylight Saving Time!
