• Introduces copyPasteUtils with configuration, reader/writer interfaces, and conflict strategies
• Adds DemoTask and CopyPasteCollectionTask to execute and monitor copy operations via the Task framework
• Registers copyCollection/pasteCollection commands, global state, and localization updates

[nitpick] Remove or update placeholder comment 'Add commentMore actions' to clarify intent or link to a tracking issue.

Suggested change

	// Check type of sourceNode or targetNodeAdd commentMore actions
	// Currently we only support CollectionItem types
	// Later we need to check if they are supported types that with document reader and writer implementations
	// Verify that both sourceNode and targetNode are of type CollectionItem.
	// Currently, only CollectionItem types are supported.
	// Future work: Extend support to other types with appropriate document reader and writer implementations.
