Fix annotation button errors and add working E2E tests

- Fix 'closest is not a function' error by checking if target has closest method
- Fix 'Invalid string length' error in error capture by limiting JSON stringify length
- Fix Playwright config to use persistent context for extension loading
- E2E tests now properly load extension and test annotation button
- Tests capture browser errors automatically
- All feature tests passing
