Refactor DiggingTask and embed it in Tasks enum

- Remove lifetime and path storage from DiggingTask, make it Copy.
- Add a placeholder `new` constructor that accepts a path.
- Update the Tasks enum to hold a DiggingTask value.
- Reorder module declarations and re‑export order for tasks.
- Add a commented‑out tasks field to MinerUnit as a preparation step.
