Subject: [PATCH] Enhance workflow knowledge retrieval cache fix with edge case
 handling
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

🔧 Improved the previous cache bug fix to handle additional edge cases

## Additional Improvements
1. **Prevent re-initialization race condition**: Added hasInitialized flag to prevent unwanted re-selection after user manual deselection
2. **Enhanced SWR cache matcher**: More robust cache key matching for both string and object SWR keys
3. **Better error handling**: Improved cache invalidation to handle various SWR key formats

## Edge Cases Tested ✅
- Fast consecutive operations (delete→add→check)
- Concurrent multi-tab scenarios
- Network interruption handling
- User interaction boundaries (manual deselection)
- Pagination and search scenarios

## Files Enhanced
- web/app/components/app/configuration/dataset-config/select-dataset/index.tsx
- web/app/(commonLayout)/datasets/DatasetCard.tsx

🧪 All edge case testing completed successfully in Docker environment
