Spec for adding srccfg-vocab autocomplete to the runtime console input
on server-detail. Reuses the editor's ranking algorithm (extracted to a
shared module) but ships a small vanilla dropdown so the console stays
independent of CodeMirror. Tab/Esc drive the dropdown; ArrowUp/Down keep
recalling history; Enter always submits the typed text, never the
highlighted suggestion.
