pub const KNOWN_BUILTINS: &[&str];Expand description
Command names that cmd_man accepts as a man-page fallback when the name
is not yet wired into the live clap subcommand tree.
FE-13: after the apcli group restructure, the 13 former root-level
built-ins live under apcli (e.g. apcli list). This constant retains
the flat names for the v0.7 deprecation window so legacy invocations like
apcore-cli man list still render useful output. Keep the set in sync
with the spec ยง4.1 subcommand table plus the root-level man meta.
