Namespaces, assemblies, projects and directories, the solution, binaries, images, systemd units, config paths, environment variables, protocol method names, the media type and the raw chunk magic all move to MoShiro/moshiro. Existing data and deployments are not compatible and must be recreated. Also fix the architecture tests after the solution layout change and make the update tests independent of their order.
