// Skip the .NET SDK first-run experience. On macOS Helix machines, the
// first-run HTTPS dev cert generation hangs for >2 minutes, causing the
// HelixTestRunner timeout to kill the dotnet process (exit code 130).
//
// DOTNET_SKIP_FIRST_TIME_EXPERIENCE is deprecated and no longer honored
// in .NET 8+. The replacement is individual controls:
// - DOTNET_NOLOGO: suppresses the welcome banner
// - DOTNET_GENERATE_ASPNET_CERTIFICATE: skips dev cert generation (the hang)
