Four release-note bullets describing the user-visible changes shipped
in this round:
- async-spawn install/update/uninstall (UI no longer freezes)
- phase-based install progress bar (Preparing through Finalizing)
- scanner kick post-install (Launch button appears immediately)
- .23 Hetzner VPS retired, .168 OVH promoted to Server 1 with
auto-purge migration for existing nodes
Matches the tone of existing changelog entries: what changed from the
operator's perspective, not internal implementation detail.
