"""
Alias the real dataset package so that `import src.dataset` works.

This module ensures that `import src.dataset` and
`from src.dataset.problem_X.buggy import ...` statements work correctly
by aliasing the real dataset package and all its nested submodules.

This is needed because:
- Test files import from `src.dataset.problem_X.buggy`
- But the actual files are in `dataset/problem_X/buggy.py`
- So we create sys.modules aliases to bridge the gap
