"""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.
