Delete a file

Permanently delete a file and all associated data.

Requirements:

• Delete permission on the document
• Workspace must allow manual document management (not sync-only)

Public datasets: deleting a public-dataset file requires the instance-admin MANAGE_PUBLIC_DATASET permission. A workspace-scoped API key with read access (company opted in via allow_access_to_public_datasets) can see the file but gets 403, not 404, when attempting to delete it — public datasets are read-only.

Returns 204 (No Content) on success.
