New bin/gstack-relink creates prefixed (gstack-*) or flat symlinks based on skill_prefix config. gstack-config auto-triggers relink when skill_prefix changes. Setup guards against recursive calls with GSTACK_SETUP_RUNNING env var. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
