- Replaced `Subject|array` return types with `SubjectBag` in `SubjectConverterInterface` for more robust handling.
- Updated `getSubjectsForEntity` to include an optional `$includeAssociated` parameter for finer control over associated subject resolution.
- Refactored `AuditEvent` to differentiate `mainSubject` from associated subjects, improving clarity in audit logging.
- Introduced database schema changes to add `main_subject` and `subjects` columns in the `chill_main_audit_trail` table.
- Added `SubjectBag` class for grouped subject management and implemented deduplication logic.
- Updated all converters and test cases to use the new `SubjectBag` approach, ensuring compatibility.
- Improved event dispatching in controllers to utilize the updated `AuditEvent` structure and refined metadata handling.
- Removed `convertEntityToSubjects` method from `SubjectConverterManager` and updated all references to use `getSubjectsForEntity`.
- Ensured `getSubjectsForEntity` always returns an array by wrapping single `Subject` instances.
- Replaced manual type handling in converters with `array_push` and improved code clarity in `AuditEvent2Trail` and related tests.
- Updated and fixed tests for the modified subject conversion logic to maintain coverage.
- Introduced `SubjectConverterManagerAwareTrait` and `SubjectConverterManagerAwareInterface` for injecting subject converter manager into converters.
- Added `getSubjectsForEntity` method in `SubjectConverterManager` to centralize subject retrieval logic.
- Updated converters to set the subject converter manager when applicable.
- Implemented `AuditEvent` class to represent audit events.
- Added `AuditEvent2Trail` for converting events to audit trails.
- Introduced `Subject` and `SubjectConverterManager` for subject conversion.
- Created contracts like `SubjectConverterInterface` and `AuditEvent2TrailInterface`.
- Developed `AuditEventSubscriber` to persist audit events using `AuditTrailPersister`.
- Included test classes for core audit services and components.
