pub fn advanced_help_groups() -> Vec<(&'static str, Vec<&'static str>)>Expand description
Area groups for the heddle help advanced listing, in render order,
as (display title, verbs) pairs (heddle#652). The grouping is
contract-table data, not a hand-maintained help string: native
advanced commands carry an explicit help_category on their
registration, while automation / admin / git_adapter commands
derive their group from the surface they already declare. Verbs keep
contract order (help_rank, then name) within each group — the same
ordering the flat list used. Feature-gated verbs absent from the
current build simply don’t appear; a group may come back empty.
