fix: sync wrapper with v11-v13 binary changes

- Rename --timezone to --fingerprint-timezone (breaking binary change in v13)
- Remove --fingerprint-taskbar-height from defaults (binary auto-applies per platform)
- Update viewport height 955→947 (48px Win taskbar default)
- Update patch count 26→25 (patch 003 deleted in v11)
- Document new flags: --fingerprint-fonts-dir, --enable-blink-features=FakeShadowRoot, --fingerprint-taskbar-height (optional override)
- Fix README: remove incorrect "defaults to windows" claim
