Switch the containerization dependency from the github URL to a vendored copy (third_party/containerization, upstream commit 6b7b42ca) referenced by path, so we can carry a small local patch that upstream lacks: LinuxContainer.Configuration gains a `vmExtensions` field forwarded into VMConfiguration.extensions. Upstream already supports VMConfiguration.extensions + the VZInstanceExtension hook, but LinuxContainer — our only entry point — never forwarded them, so there was no way to attach a device (e.g. a memory balloon) to a container's VM. Tests/, docs/, examples/, images/ and the corresponding test targets are trimmed for footprint (we never build the dependency's tests). See PATCHES.md for the full diff vs. upstream and the re-vendoring procedure. Also adds the ContainerizationExtras product to NucleicCore (AddressAllocator, named in the configureVZ signature).
