Work and attempts

Work is the requested outcome. An attempt is one try to complete it.

excellent run --agent "your-agent" --task "Add CSV export"

Expected result: Excellent creates an attempt record and binds it to the repo state and agent setup.

If an attempt is returned, the next attempt links back to the prior one. The prior attempt is not rewritten.

Undo accepted work with the rollback path shown in the result.
