claude fbec36cb67 feat(course): build out all 27 modules, capstone, scaffold, and conventions
Scaffold the course repo and author the full curriculum in dependency-chain
order, following the settled build decisions in handoff.md.

- Scaffold: course README, vendor-neutral AGENTS.md (dogfoods Module 5),
  _TEMPLATE.md (the fixed 9-section module shape), root .gitignore, ship config.
- Modules 1-2: reference exemplars (locked for tone/depth/lab style).
- Modules 3-27: full lessons + runnable labs, each following the template,
  respecting the chain, vendor/model-agnostic, with "feel the pain" labs.
- Module 8 hosting comparison web-researched and date-stamped (as of 2026-06-22),
  not written from memory; expansion-zone modules carry Verify-before-publish.
- Capstone: the full loop end to end on the running tasks-app example.

Lab code syntax-checked (Python/shell/YAML); every module has the 7 core
template sections.

"""Tiny command-line front end for the demo task app.
Run it:
python cli.py add "write the lesson"
python cli.py list
python cli.py done 0
State is kept in tasks.json next to this file. The `done` command turns a bad index into a
clean error message and a non-zero exit code — note that behavior before you review the AI
change, so you can tell if the change quietly alters it.
