CI / check (pull_request) Successful in 7s
feat(labs): make every lab a self-contained, skip-friendly starting point
Each lab now stands on its own; no hard dependency on prior labs.
- App-based labs get a canonical tasks-app snapshot in lab/start/ (three
  baselines: v0 add/list/done; v1 +count; v2 +count/delete), assigned by where
  each module sits in the command timeline. Modules with a purpose-built app
  (M10 trap, M13 planted bug, M21) snapshot their own app; planted devices kept.
- Self-contained labs (M15/17/18/19/22/23/24/25/27, which operate on their own
  lab files) get a preamble pointing at modules/NN/lab/.
- Every module + capstone gets a "Starting point (skip-friendly)" preamble:
  copy the snapshot, git init -b main, commit -> clean status, then start.

Lets a learner skip around or recover: copy start/, commit, go. All snapshots
run; tools/check.sh passes; no em-dashes.

"""Tiny command-line front end for the demo task app.
Run it:
python cli.py add "write the lesson"
python cli.py list
State is kept in tasks.json next to this file. It's intentionally minimal; the point of this app
is to be a realistic-but-small thing you change with an AI, not a product.
