## Context / problem
`python cli.py done 99` on a list with 3 tasks raises an uncaught `IndexError` and dumps a Python
traceback. `python cli.py done abc` raises `ValueError` the same way. The user sees a stack trace
`python3 cli.py done 99` on a list with 3 tasks raises an uncaught `IndexError` and dumps a Python
traceback. `python3 cli.py done abc` raises `ValueError` the same way. The user sees a stack trace
instead of a helpful message, and the process exits as if it crashed.
Reproduce:
```
python cli.py add "first"
python cli.py done 99 # IndexError traceback
python cli.py done abc # ValueError traceback
python3 cli.py add "first"
python3 cli.py done 99 # IndexError traceback
python3 cli.py done abc # ValueError traceback
```

## Acceptance criteria
- [ ] `python cli.py undone <index>` clears the done flag on the task at that index and saves.
- [ ] `python3 cli.py undone <index>` clears the done flag on the task at that index and saves.
- [ ] `undone` with an out-of-range or non-integer index prints a clear error and exits non-zero
(same behavior as the fixed `done`, see Issue 1).
- [ ] `list` after `undone` shows that task as not done (`[ ]`).
