Kros DaiandClaude Opus 5.5 e121561851 ✨ feat(install): pick the region from the timezone
- ✨ the timezone the user already chose selects the region, so no new prompt is needed
- 🔒 populate only the selected region's keys so global installs never trust them
- ✅ cover the mapping, autoinstall override, marker, keyring setup, and builder staging
