4.13.0 — Consistency & device fingerprint update

Fixed:
- Accept-Language header now always matches the Navigator language setting — no more mismatch between JS and the HTTP header.
- Fixed an issue causing YouTube playback to restart partway through (video/streaming infrastructure excluded from header spoofing).
- Whitelisted domains are now fully exempt from both JS fingerprint patches and HTTP header spoofing (previously JS only).
- Fixed a Firefox-specific inconsistency where navigator.vendor didn't match a real Firefox install.
- IP geolocation and VPN detection are now more reliable on networks with strict DNS filtering.

New:
- Device (OS + GPU) section: Auto (matches your real device, recommended) or manually pick a realistic Windows/macOS/Linux + GPU combination — platform, WebGL renderer, User-Agent, and Sec-CH-UA-Platform now change together, consistently.
- Manual screen resolution override.
