fix: simplify resource resolution for subdirectory baseURL deployments

The previous complex fix had bugs in the path parsing logic. This simpler approach
directly handles the common case where Hugo tries to resolve resources with the
baseURL path prefix, which fails with resources.Match.

This fix:
- Directly strips known problematic prefixes
- Uses a cleaner fallback approach
- Adds debug information to help identify issues
