The repo documents its own build and test commands, but assumes Windows and
PowerShell. This captures only the deltas that make them run on this machine:
dotnet from nixpkgs, artifactory credentials sourced per command because shell
state does not persist between tool calls, and a curl check that distinguishes
an auth failure from a code failure, since a rejected token surfaces as a
NuGet error that reads like a network fault.
Also records the two Docker Desktop leftovers that break the component test
environment, and the unleash registration a component test canary needs.
