  print prominent error and Environment.Exit(1)

  (appsettings + env); default disabled
- HTTPS: ForwardedHeaders (when enabled) and Https:UseRedirectAndHsts
  (appsettings + env); default disabled
- HttpClient: IHttpClientFactory + SameHostBaseAddressHandler for same-host
  API calls; default client uses Options.DefaultName
- publish-self-contained.sh: platform auto-detect, clean before publish,
  --no-clean option, RIDs including ubuntu.*-x64/arm64, linux-musl-*
- prepare-test-mount.sh: stop/tidy options
- EnsureManagedConfigHostedService / DnsmasqConfigSetService: managed
  config path and conf-file= handling

# Run the app with real dnsmasq and a DHCP client so hosts/leases are real.
# Prepare mount: ./scripts/prepare-test-mount.sh [--prepare-only | --no-build | --recreate | --source DIR | --mount DIR]
# Or set TESTDATA_MOUNT to override the data volume (default: ./testdata-mount).
#
# app builds from Dockerfile (app + dnsmasq in one container; app is main process).
# ReloadCommand/StatusCommand use pkill/pgrep (procps in image). cap_add NET_ADMIN for dnsmasq.
#
# Networks: testnet 172.28.0.0/16 so dnsmasq can hand out 172.28.0.10–50.
