docs(plugin): say where Copilot CLI's plugin comes from, and what to do about the skills catch

Copilot CLI's marketplace step installs the plugin from this repository's main branch,
not from the OpenRig package the other apps use, so its skill can be newer than the
OpenRig a person runs. And when Copilot CLI picks OpenRig's own skill router from
~/.agents/skills, it can ask for a skill pack that isn't there: the README now says to
ask it to use working-with-an-openrig-team.
