refactor!: rename the project from Monitor to MoShiro

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.

 """跨机器的真实链路验证：Windows 上的 Probe（NativeAOT exe）→ WSL2 里的 Agent 和 Backend（真实的虚拟网络、不同的单调时钟原点）。
 
 前提：WSL 里有 Debian（root）、tc（netem 注入丢包/延迟/黑洞用）；已经用 scripts/publish.sh 发布了 linux-x64 的 agent、backend、fleet-enroll，
-并且 Windows 上发布了 probe（dotnet publish backend/probe/src/Monitor.Probe -c Release -r win-x64 -p:PublishAot=true -o backend/artifacts/aot-probe）。
-把 linux-x64 的产物复制到 WSL 的 /root/mon/，在 WSL 里用 setsid -f nohup 启动 monitor-backend（监听 0.0.0.0:29181），再运行本脚本。
