Kros DaiandClaude Opus 5.5 3c68a1bb04 ✨ feat(region): put the china channel mirrors first
- ✨ omarchy now runs per-channel china replicas, so they should lead instead of trailing as a fallback
- ♻️ prepend per-channel fragments so each channel's own mirror stays the fallback
- 🔥 drop the ustc arch mirror, which was never a stable or rc snapshot replica
