This release focuses on code quality improvements, bug fixes, and enhanced reliability.

Improvements:

• Code Quality: Comprehensive refactoring to improve maintainability, error handling, and logging throughout the codebase
• Error Handling: Enhanced error handling in core controllers, webhook, and kubelet metrics collection
• Logging: Improved logging consistency and clarity across all components
• Annotations: Better handling of default scale-up values and annotation parsing
• Testing: Improved E2E test reliability and error handling

Bug Fixes

• Fixed various edge cases in PVC controller, PVCGroup controller, and PVCPolicy controller
• Resolved issues in webhook certificate generation script
• Improved cache storage and kubelet metrics handling
• Fixed annotation policy application logic

• PVCGroupCR was added
• improved e2e and unitest coverage
• misc bugfixes

• PVCPolicy CRD: Added policy-based configuration with label selectors for centralized PVC management

• Enhanced E2E Testing: Comprehensive test suite with minikube integration and policy validation

• Policy Controller: New controller for managing PVCPolicy resources with namespace-scoped policies

• Configuration Hierarchy: PVC annotations → PVCPolicy → Global flags → Defaults precedence order
