feat: migrate anime2 scraper from alqanime.si to alqanime.net

- Change BASE_URL from https://alqanime.si to https://alqanime.net
- Remove BASE_DETAIL_URL (now same as BASE_URL)
- Remove detail_image_url method (no longer needed)
- Simplify detail() use case: remove dual-fetch logic that merged
  results from both domains (now same URL)
- Fix CLAUDE.md stale comment
