Add AnyClip integration tools and extracted source code

- Add authentication scripts with SubtleCrypto password encryption
- Add sourcemap extraction pipeline (update-urls, download-sourcemaps, extract-sources)
- Add Playwright API interception script for monetization endpoints
- Document two-step auth flow with JWT tokens and dual cookies
- Move extracted source from root to anyclip/ directory
- Add project configuration (.env.example, .gitignore, CLAUDE.md)
