Add centralized HELP with per-command subcommands

New echo-api primitive: a HelpEntry table plus a shared help() renderer.
HELP lists a service's commands; HELP <command> prints that command's
detail. Every service routes its HELP arm through the one renderer, so
the shape is identical across the network. Wired into NickServ and the
six newer services so far.
