Greptile Summary

• Changes the condition from if (storeValue) to if (storeValue != null) in the GenericSyncWrapper component's useEffect to allow empty string parameter values to trigger synchronization
• Fixes a bug where tool parameters couldn't be properly cleared since empty strings were treated as falsy and skipped during store-to-UI synchronization
