Spoof-when-possible browser personas, Tier-2 telemetry kill + artifact wipe, UI polish

Browser: identity persona dropdown (blend Windows-Chrome / Firefox / mac-Safari / hardened / custom) + cookie policy dropdown. Blend personas relax RFP/FPI/strict-TP so the machine looks normal while still hiding behind the chain. Persona TZ applied via env var; UA / language / locale / screen via user.js. WebRTC still forced off (it leaks real IP). Privacy: Telemetry kill toggle (DiagTrack, Activity History, ad ID, Cortana, scheduled tasks) with full snapshot/restore. One-button forensic artifact wipe (TEMP, Recent, Jump Lists, Prefetch, MRU, clipboard). UI: neon palette, glow card borders, gradient header banner.
