[WIP] Fix ImageBuilder to start and manage application host
Start and dispose the generic application host in ImageBuilder
Jun 1, 2026
Replace the static `Lazy<IHost>` on `ImageBuilder` with a `CreateAppHost()` factory so the composition root (`Program`) unambiguously builds, owns, and disposes the host. Resolve commands directly via `GetServices<ICommand>()` and drop the static `Services`/`Commands` accessors. `StandaloneLoggerFactory` now owns a settable `ILoggerFactory` (defaulting to `NullLoggerFactory.Instance`) that `Program` wires from the host, instead of reaching into a static service provider. Convert `McrTagsMetadataGenerator`'s type-load-time static logger field to a property so it no longer captures the default factory before `Program` configures logging.
