Clean up obvious and redundant comments that don't add value:
- Remove step-by-step comments in command handlers
- Remove obvious test setup comments
- Keep only meaningful comments that explain why, not what
Following TDD principles, adding tests before implementation:
- Add HabitType value object tests (validation)
- Add Frequency value object tests (validation)
- Add User entity tests (creation, default timezone)
- Add Habit entity tests (creation, archive, active status)
- Add HabitEntry entity tests (creation, soft delete)
Tests cover core domain logic and business rules.
All tests will fail until implementation is added.
