fix(cmdk): Apply prefix to nested See all actions

See all items in nested search results now receive the same prefix label
as their sibling actions (e.g. 'Explore → See all' instead of bare 'See all').

The :see-more key is added to prefixMap with the intermediatePath alongside
the existing :source-label hint, which is unaffected.
