imfozilbek c75738ba51 feat: add aggregate boundary validation (v0.7.0)
Implement DDD aggregate boundary validation to detect and prevent direct
entity references across aggregate boundaries.

Features:
- Detect direct entity imports between aggregates
- Allow only ID or Value Object references
- Support multiple folder structures (domain/aggregates/*, domain/*, domain/entities/*)
- Filter allowed imports (value-objects, events, repositories, services)
- Critical severity level for violations
- 41 comprehensive tests with 92.55% coverage
- CLI output with detailed suggestions
- Examples of good and bad patterns

Breaking changes: None
Backwards compatible: Yes

* Interface for detecting aggregate boundary violations in DDD

* Aggregate boundary violations occur when an entity from one aggregate
* directly references an entity from another aggregate. In DDD, aggregates
* should reference each other only by ID or Value Objects to maintain
