Greptile Summary

This PR fixes the action bar duplicate functionality to properly include children when duplicating loop/parallel blocks. The implementation refactors handleDuplicateBlock to use the copyBlocks + preparePasteData pattern from the workflow registry, which automatically handles nested block inclusion and ID regeneration. It also adds trigger validation to prevent invalid duplications and error notifications when conflicts occur.

Changes:

• Replaced manual block duplication logic with copyBlocks() + preparePasteData() pattern
• Added validateTriggerPaste() validation to check for trigger constraints
• Added error notifications for validation failures
• Properly passes all required parameters to collaborativeBatchAddBlocks() including edges, loops, parallels, and subblock values
• Updated dependencies in useCallback to reflect the new logic flow

Confidence Score: 5/5

• This PR is safe to merge with no concerns
• The refactoring uses well-established patterns already present in the workflow.tsx file's executePasteOperation function. The copyBlocks function automatically includes children via its built-in loop/parallel node detection. The preparePasteData and regenerateBlockIds functions properly handle ID mapping, reference updates, and position offsetting for nested blocks. The addition of validateTriggerPaste validation strengthens the implementation by preventing invalid duplications. The code follows existing patterns, maintains proper state management, and includes appropriate error handling.
• No files require special attention
