fix: improve CI artifact restoration with flexible path detection

- Add debug output to show available artifact structure
- Support multiple possible artifact directory layouts
- Add fallback logic to handle different upload patterns
- Ensure proper directory creation before copying files

This should resolve the sitemap validation failures by properly
restoring build artifacts to expected locations.
