Scaffold Exercises

Create exercise directory structures that pass linting, then commit with git commit.

Directory naming

• Sections: XX-section-name/ inside exercises/
• Exercises: XX.YY-exercise-name/ inside a section
• Names are dash-case (lowercase, hyphens)

Exercise variants

Each exercise needs at least one of these subfolders:

• problem/ - student workspace with TODOs
• solution/ - reference implementation
• explainer/ - conceptual material, no TODOs

Required files

Each subfolder needs a readme.md that is not empty and has no broken links.

Workflow

1. Parse the plan - extract section names, exercise names, and variant types
2. Create directories - mkdir -p for each path
3. Create stub readmes - one readme.md per variant folder with a title
4. Run lint - validate
5. Fix any errors - iterate until lint passes
