runDescribeCli function
CLI adapter for fdb describe. Accepts no flags; emits a compact
text snapshot of the current screen:
SCREEN: <screen> (if present)
ROUTE: <route> (if present)
<blank line> (if screen or route was printed)
INTERACTIVE: (if interactive list non-empty)
[<Ancestor> ["text"] [> ...]] (breadcrumb — only if meaningful)
@N <type>[(gestures)] ["text"] [key=<key>]
<blank line>
VISIBLE TEXT: (if non-duplicate texts exist)
"<text>"
Implementation
Future<int> runDescribeCli(List<String> args) => runCliAdapter(ArgParser(), args, _execute);
