[Feature Request] Add a beginner-friendly cheatsheet for data hyper-cleaning operator combinations

[pipi-183]

Required prerequisites

• I have searched the Issue Tracker to make sure this feature request has not already been submitted.
• I have checked the documentation https://boat.readthedocs.io/en/main/ to confirm this feature is not already supported.

Motivation

I am learning BOAT through the examples/data_hyper_cleaning/test_data_hyper_cleaning.py example. The example is useful because it includes many bilevel optimization operator combinations, such as NGD, GDA, DI, DM, CG, RAD, FD, NS, IGA, VSO, VFO, MESO, and PGDO.

However, as a new user, I found it difficult to quickly understand which combinations belong to GM-OL, NA-OL, and FO-OL, and which combinations are recommended for beginners to run first.

This is related to the data hyper-cleaning use case. Since BOAT is configuration-heavy, a beginner-friendly cheatsheet would reduce confusion and help new users run the examples more smoothly.

Proposed solution

I suggest adding a short cheatsheet to the documentation or to the examples/data_hyper_cleaning README.

The cheatsheet could include:

1. Recommended beginner combinations, such as NGD + CG, GDA + CG, and NGD + RAD.
2. A table explaining which operators belong to GM-OL, NA-OL, and FO-OL.
3. Common invalid or confusing combinations that users should avoid.
4. A short explanation of what each operator combination is intended to test.
5. A minimal command for running one stable data hyper-cleaning example.

This would make the data hyper-cleaning example easier to understand and reduce trial-and-error configuration mistakes.
