Read tests/Shared/Hex1bAutomatorTestHelpers.cs at line 176 and tests/Aspire.Cli.EndToEnd.Tests/DockerDeploymentTests.cs at line 48; reproduce the named test and inspect why the `aspire` command is unavailable in the temporary workspace. Done means CreateAndDeployToDockerCompose completes in the Ubuntu CI environment and the `aspire new` template-selection step is reached.
