v0.2.234

Fix: Dashboard no longer crashes at startup on Linux arm64 / aarch64.

The previous release used a shared-framework Docker image where the
.NET assembly loader couldn't resolve System.Private.Xml during
Blazor's MapRazorComponents setup. We've switched to a self-contained
publish on a runtime-deps base — the entire .NET 8 runtime ships inside
the image now, so the dashboard's assembly resolution never has to leave
the published output.

End-user impact: a fresh docker compose up -d now actually boots and
you land on the setup wizard.

No other changes since v0.2.232.
