Delete Template

Delete a template owned by the caller’s workspace.

The delete is a soft delete — the record is hidden from the gallery and all visibility checks immediately, but is not physically removed. Any workflows previously cloned from this template are unaffected; clone creates an independent copy of the definition at clone time.

Restrictions:

• Only the owning workspace may delete its templates (403 otherwise).
• Platform starter templates (is_starter=true) cannot be deleted (403).

Requires workspace editor role or higher.
