feat: upgrade to Chromium v145 with Patchright CDP stealth

- Migrate from Playwright to Patchright driver for CDP leak prevention
- Add screen dimension spoofing args (--fingerprint-screen-width/height, --fingerprint-taskbar-height)
- Add realistic default viewport (1920x955) to avoid Playwright detection
- Add color_scheme param to launch_context, add fingerprint scan test
- Update READMEs for v145
