* Shared picker for the "anywhere in the vault" capture scopes (tag, property): * the matched notes can live in any folder, so the picker shows full paths. The * "Create new note" affordance is suppressed for any name that already exists * in the vault (by path or basename, in any folder), so

		notFoundMessage: string,
