Paranoid 4-pass review found 7 issues, all fixed:
- Add ETHOS.md to create_codex_runtime_root
- Clean old real dirs (not just symlinks) on upgrade
- Skip runtime root for repo-local installs (prevent self-referential symlinks)
- Add review/, ETHOS.md, gstack-upgrade/ to Kiro install
- Update gstack-upgrade to detect ~/.gstack/repos/ and .agents/skills/
- Guard --host without value from silent exit
- Fix Kiro sed patterns + timeout instruction in gen-skill-docs.ts
