Greptile Summary

Refactored change detection hook to use the shared mergeSubblockStateWithValues helper instead of duplicating the merge logic inline. This eliminates code duplication and ensures consistent subblock merging behavior across the codebase.

• Removed 38 lines of inline subblock merging logic
• Added import for mergeSubblockStateWithValues from @/lib/workflows/subblocks
• The helper correctly handles null/undefined filtering and creates default subblock structures for values without existing definitions
• Maintains identical behavior to the previous implementation after the fix in commit 7c5a6bd

Confidence Score: 5/5

• This PR is safe to merge with no risk
• This is a straightforward refactoring that replaces duplicate inline logic with a shared helper function. The helper function performs the exact same operations with identical behavior, including proper null/undefined filtering. The change improves code maintainability by consolidating subblock merging logic that was previously duplicated across multiple files.
• No files require special attention
