feat(timer): show timer widget on all first-level tasks

Changed task timer display logic to show timer widgets on all first-level (top-level) tasks,
not just those with subtasks. This provides more consistent timer functionality across all
main tasks while still excluding completed and abandoned tasks.

- Add minimum indentation level detection
- Replace subtask requirement with first-level task check
- Update logging to reflect new logic
