Backup Physical Memory Modules to JSON (C#)

// BackupPhysicalMemoryListToJson.cs
//
// Snapshots Physical Memory Modules (Win32_PhysicalMemory) to a timestamped JSON file.
//
// Requires the System.Management package:
//   dotnet new console -o BackupPhysicalMemory
//   dotnet add package System.Management
//   (replace the generated Program.cs with this file, then dotnet run)
