Remarks
The cancellationToken is propagated from Host.StartAsync(CancellationToken). By default, no startup timeout is applied. Configure HostOptions.StartupTimeout or pass a CancellationToken with a timeout to Host.StartAsync to bound I/O-bound async validators:
builder.Services.Configure<HostOptions>(opts =>
opts.StartupTimeout = TimeSpan.FromSeconds(30));
