-/// `SingleMatcher` is a composite matcher for single-value parameters.
-///
-/// It delegates to [`PositionalMatcher`] for positional args and
-/// [`ArgMatcher`] for named args, adding a guard: if a named flag
-/// captures only itself with no inline value (eq mode), the result
-/// is cleared so that [`Pickable::pick`](crate::Pickable::pick) receives `[]` → `NotFound`.
-///
-/// This is the standard tag implementation for all `Single`-type
-/// `Pickable` implementations (e.g., `String`, `i32`, `u64`).
