One ordered member of a named group's membership list. A 'state'
member is an ordinary state (a inside &g : [a]). A 'group' member
references another group: mode: 'nest' is the &child form, which
preserves the child group's identity for later precedence/viz, while
mode: 'spread' is the ...&child form, which inlines the child's
members and erases that identity. Both modes resolve to the same flat
set of states via JssmGroupRegistry resolution; only their
structural bookkeeping differs.
