feat: Add Puppeteer humanize support and fix Playwright humanize gaps (#129)

- Add full Puppeteer humanize implementation (page, frame, element handle patching)
- Fix critical Playwright gaps: page.pressSequentially, page.tap, page.clear
- Fix frame-level patching: frame.pressSequentially, frame.tap
- Add comprehensive stealth tests for Puppeteer
- Update SLOW test suite to use correct humanize: true API
- Add 4 new tests validating fixed Playwright methods
