Unable to re-create option

**Describe the solution you'd like**
An option to mark a task as 'Unable to re-create' would be useful.

I use taskbook to keep track of bugs. Sometimes I'm unable to re-create an issue, and I'm left with the option to either delete, or mark the task as complete.

An example in context would be:
```
Options
...
--unable, -u Unable to re-create
...
```

1. ☐ Read jq manual https://stedolan.github.io/jq/manual/
2. ✔ configure iterm w/ word hopping, tmux scrolling 2d
3. ❓ Unable to re-create cache bug on ProductMicroService

The issue does not name any files, tests, or entry points. Start by locating the CLI option definitions and the code that renders task states, then trace how completion and deletion are handled. Done means users can mark a task as “Unable to re-create” with the proposed option and see that state in task output.
