refactor: reorganize scripts - move debug code to experiments/

- Move debug/test scripts from src/scripts/ to experiments/
- Remove test-detail-endpoint from package.json
- Delete temp-product-page.html
- Move E2E_GUIDE.md to docs/
- Add experiments/README.md with documentation
- Keep only production scripts in src/scripts/
- Clean up tsconfig.json exclude list (experiments are now outside src/)
