media: gallery settings (absolute folders, deduplicated), listing and
resolving images only directly inside owner-chosen folders (links must
stay inside), data URLs, the bounded clipboard history with its index
and image files, PNG encoding. media::clipboard (tauri feature): reading
the OS clipboard, the Windows change counter, skipping copies marked
private by password managers, and the opt-in polling loop (records from
the next copy after opting in; releases the clipboard while off).
