Garry Tan a99162db66 feat: add update check preamble to all 9 skills ... Every skill now runs bin/gstack-update-check on invocation. If an upgrade is available, reads gstack-upgrade/SKILL.md inline upgrade flow. Also adds AskUserQuestion to 5 skills that lacked it (gstack root, browse, qa, retro, setup-browser-cookies) and Bash to plan-eng-review. Simplifies qa and setup-browser-cookies setup blocks (removes META parsing).		2026-03-13 23:57:19 -05:00
