Move this other weird claude code

- Implements configurable custom strings for restock detection (fixes #2779)
- Adds robust text normalization (case-insensitive, accent removal, whitespace)
- Supports international sites with custom messages like 'Pronto estarán en stock\!'
- Makes built-in in-stock detection configurable (addresses TODO)
- Includes comprehensive unit and integration tests
