How to run

1. either set ANTHROPIC_API_KEY environment variable, or add an apiKey param where new Anthropic() is called in playwright-plugin.ts
2. pnpm install
3. the example tests are in aistuff.test.ts, its just a normal test file, any playwright features should work as expected
4. pnpm exec playwright test . to run the tests

Note: This is a super simple POC, things may break, and the code is trash.
