The Desktop/TUI/dashboard toggle edited the saved list before the plugin
loaded, so a backend that scanned while the plugin was off found no toolset
key and left the toolset out: the plugin showed enabled with its tools off.
Enable now edits the list after activation; disable resolves the key before
the disable is written. hermes plugins enable/disable make the same edit.
Only saved lists are touched; a fresh config still gets no list.
