feat: initial public release

Stealthfox — a patched Firefox 150.0.1 for browser-fingerprint stealth,
shipped as a Playwright-compatible Python wrapper.

  * Sync + async Stealthfox launcher (firefox_user_prefs, virtual desktop
    on Windows, SOCKS5 auth via patched nsProtocolProxyService)
  * fpforge: Bayesian fingerprint sampler over GPU / audio / fonts /
    screen / TCP options / ~400 other navigator fields
  * WebRTC stealth: srflx address swap, synthetic srflx fallback,
    private-LAN host candidates — no real public IP leak via STUN
  * GPU sandbox fix for FF150 alt-desktop regression
  * Bezier-curve mouse motion baked into Juggler

Targets Windows x86_64 + Linux x86_64. Binary fetched on first run from
GitHub Release "firefox-1".
