Root AGENTS.md pointer file per the architecture decision in discussion #78: documents both config roots (.agents/skills/ portable portal skills, .claude/ orchestration) and the profile entry points, carries a framework_version marker registered in both version tools.
Design case made by @erikpr1994 in the #78 architecture thread; implementation by @jovin-nicholas.
* Add framework_version markers to assistant skills and implement CI version guard and update checker
* Address review feedback: update ci.yml based on latest upstream, gate CI version guard to upstream repo, and remove non-ASCII characters from check_upstream_updates.py
