PlanError reports a plan this package refused before sending anything to tmux. It matches [ErrPlan] through errors.Is; callers can recover Step and Reason with errors.As.

## Members

- `Step` (attribute) — Step is the zero-based index of the operation at fault.
- `Reason` (attribute) — Reason describes what makes the plan unrunnable.
- `Error` (method) — Error implements error.
- `Unwrap` (method) — Unwrap makes PlanError compatible with ErrPlan.
