Test scenarios:

1. Installed from local checkout with specify extension add --dev /home/administrator/github/spec-kit-arch.
2. Verified Codex skill registration at .agents/skills/speckit-arch-generate/SKILL.md.
3. Ran .specify/extensions/arch/scripts/bash/setup-arch.sh --json and verified the six expected architecture files were created under .specify/memory/.
4. Published v1.0.0 and installed from https://github.com/bigsmartben/spec-kit-arch/archive/refs/tags/v1.0.0.zip in a fresh project.
5. Re-ran the setup helper after release ZIP installation and verified the same six architecture artifacts.
