Reusable, generics-based CLI extracted from vpp-evpn's cmd/evpnc:
a declarative command tree (Node[C]) from which dispatch, '?'-help and
TAB-completion are derived, an interactive Shell[C], dynamic slot
resolvers (context-dependent via captured args), text-or-JSON output
(Emit), and color helpers (Paint/Label/KV). Builds on Linux and OpenBSD
(readline termios override). Includes a self-contained example and a
design proposal under docs/.
