Display the run queue as a DAG tree showing dependency hierarchy.

### `dag-queue-display` - What it does
By default, Terragrunt displays the run queue as a flat list of units before execution. When this experiment is enabled, the queue is rendered as a tree that visualizes dependency relationships between units. Independent units appear as siblings at the root, while dependent units are nested under their dependencies.

The tree also changes its header message based on execution direction:

- **Apply/Plan**: "starting with dependencies and then their dependents"
- **Destroy**: "starting with dependents and then their dependencies"

```bash
terragrunt run --all --experiment dag-queue-display -- plan
```

Example output:

```
The following units will be run, starting with dependencies and then their dependents:
.
├── monitoring
╰── vpc
    ╰── database
        ╰── backend-app
            ╰── frontend-app
```
