fix(rules): accept any questions-v*.md version + restore questions file

The required-files check pinned questions-v1.md, which breaks every time
the Q&A file versions up (v2 was closed out by the parallel session,
leaving nothing matching). Now glob-accepts any version. questions-v3.md
restores the file; active question channel is ~/PTKR.md per founder.
