NuGet package dependency

`System` is a NuGet package dependency declared by the `Pams.Storage` project. It provides .NET base library types and runtime APIs that storage code can reference during restore, build, and execution.

    Build->>Storage: Restore project dependencies
    Storage->>System: Resolve referenced APIs
    System-->>Storage: Provide .NET base types
    Build->>Storage: Build storage assembly
```

## Usage

```ts
import { execFileSync } from "node:child_process";

// Restore and build Pams.Storage so its System dependency is available.
execFileSync(
  "dotnet",
  ["build", "Pams/Logic/Pams.Storage/Pams.Storage.csproj"],
  { stdio: "inherit" }
);
```

## AI Coding Instructions

- Keep the `System` dependency aligned with the target framework configured by `Pams.Storage`.
- Restore NuGet dependencies before building or testing code that references storage types.
- Do not add JavaScript or TypeScript runtime imports for this dependency; it is resolved by the .NET project build.
- Check project references and package configuration when a `System` namespace or base type cannot be resolved.
