docling is required module after refactor

[akihikokuroda]

Importing mellea is causing loading docling now. The docling was an optional dependency and pyproject.toml still has it as optional

The README says contributors need uv sync --all-extras --all-groups. This should pull in docling

But another issue is that test_based_eval.py iscollected by pytest` - It's a module named "test-based evaluation" but pytest thinks it's a test file as it matches the default pattern

There are also some qualatative tests (I'd regard the heavy llm tests) that take a long time that I think should be skipped?
Will add notes below
