BREAKING CHANGE:
- Removed the deprecated CherryPickLogger interface from cherrypick
- Logger/adapters (e.g., talker_cherrypick_logger) must now implement CherryPickObserver
- talker_cherrypick_logger: replace TalkerCherryPickLogger with TalkerCherryPickObserver
- All usages, docs, tests migrated to observer API
- Improved test mocks and integration tests for observer pattern
- Removed obsolete files: cherrypick/src/logger.dart, talker_cherrypick_logger/src/talker_cherrypick_logger.dart
- Updated README and example usages for new CherryPickObserver model
This refactor introduces a unified observer pattern (CherryPickObserver) to handle all DI lifecycle events, replacing the limited info/warn/error logger pattern.
All external logging adapters and integrations must migrate to use CherryPickObserver.
- Introduce CherryPickLogger interface, PrintLogger and SilentLogger implementations
- Add setGlobalLogger() to CherryPick API for custom DI logging
- Log key events (scope, module, error) via logger throughout DI lifecycle
- Comprehensive comments and code documentation in both English and Russian
- Document usage of logging system in quick_start and full_tutorial documentation (EN/RU)
- Provide usage examples in docs and code comments
- No logging inside GlobalCycleDetectionMixin (design choice: exceptions handled at Scope, not detector/mixin level) and detailed architectural reasoning
- Update helper.dart, logger.dart: comments, examples, API doc improvements
BREAKING CHANGE: Projects can now inject any logger via CherryPick.setGlobalLogger; default log behavior clarified and docstrings/usage examples enhanced
