refactor: remove legacy catalog.json, use only catalog/index.json

- Remove catalog.json generation from site_generator_v2.py
- Keep only catalog/index.json (V3 lightweight format)
- Update auto-release.yml to use catalog/index.json
- Update full-build.yml to remove catalog.json references
- Revert settings.py to use catalog/index.json (correct URL)
- Fix #2: Keep if:always() on publish-metadata job

No backward compatibility needed (only dev environment, no external users)
