Pull Request Overview
This PR implements "Enhanced Nav Agent Mode", adding support for advanced persistent state management in Blazor components with enhanced navigation capabilities. The changes introduce new restore behaviors, allow state updates during enhanced navigation, and improve component state handling across different rendering scenarios.
- New restore behaviors (SkipInitialValue, SkipLastSnapshot) for fine-grained control over when state is restored
- Enhanced navigation support with AllowUpdates property for dynamic state updates
- Improved state persistence management with context-aware restoration
- Test infrastructure enhancements including filtered state properties and non-persisted counters
