docs(agent-skill): name GitHub Copilot among the CLIs that get no skill copy

Copilot's registry entry takes no agent skill, like Pi and a plain shell, but
the changeset, the App Settings help text, the Settings Reference and
CLAUDE.md named only Pi (and the shell). The Agent CLIs wiki page still said
no CLI but Claude gets the bundled skill; every CLI except Pi and Copilot
gets it, in `.agents/skills/`.

 Everything that makes a session a session works everywhere. What is Claude-only is mostly
 the machinery that needs to know *what* the agent is doing rather than *that* it is doing
