Feature Request: Add Dataset duplication feature

Overview of the Feature Request
Add a "Duplicate" button in the "Edit Dataset" menu that will allow users to duplicate an existing Dataset with all its metadata but without the associated files.

What kind of user is the feature intended for?
This feature is intended for users with Dataset creation rights (Depositor).

What inspired the request?
Currently, to create a Dataset similar to an existing one, users must manually recreate all metadata, which is time-consuming and error-prone. Adding a duplication feature will improve efficiency and user experience.

What existing behavior do you want changed?
No existing behavior will be modified. This request is for adding a new feature.

Any brand new behavior do you want to add to Dataverse?

We want to add a new "Duplicate Dataset" button to the existing "Edit Dataset" menu. When a user clicks this button:

• A new Dataset is created
• All metadata from the original Dataset is copied to the new Dataset
• The title of the new Dataset has the prefix "Copy of " (e.g., "Copy of Original Dataset Title")
• Files from the original Dataset are NOT copied
• The user is redirected to the edit form of the new Dataset to finalize its creation

Technical details:

• No relationship is maintained between the original Dataset and its copy
• Identifier uniqueness is ensured by not duplicating the DOI

Any open or closed issues related to this feature request?
SPA issue :

• IQSS/dataverse-frontend#659

Are you thinking about creating a pull request for this feature?
This is not currently prioritized in the team

Start with the existing Edit Dataset menu and the linked SPA issue IQSS/dataverse-frontend#659 to locate the current entry points. Define the duplication flow so metadata is copied, files and the DOI are not, the title gets a "Copy of " prefix, and the user reaches the new dataset's edit form. Done means the feature works for users with Dataset creation rights and preserves identifier uniqueness.
