Summary
- bump BeszelAgentManager to 4.0.1
- stop WinUI background polling during real app shutdown
- make service status
sc.exechecks bounded and quiet on shutdown - document Windows Server Desktop Experience support and enforce Windows 10 1809+ installer minimum
Root cause
The WinUI status timer could still run during application shutdown and start sc.exe while Windows service control was also shutting down. That could surface a shutdown-time sc.exe error even though normal manager behavior was working.
