NuGet package dependency

`System.Security` is a NuGet package dependency declared by the `Pams.Data` project. It provides .NET security-related types that may be required by data-layer code and is resolved during the project restore and build process.

    NuGet-->>Build: Restore dependency for Pams.Data
```

## Usage

```ts
type SecurityDependencyStatus = {
  packageName: string;
  restored: boolean;
};

function verifySecurityDependency(
  dependency: SecurityDependencyStatus,
): void {
  if (dependency.packageName !== "System.Security") {
    throw new Error("Unexpected security package dependency.");
  }

  if (!dependency.restored) {
    throw new Error("Restore NuGet packages before building Pams.Data.");
  }
}

verifySecurityDependency({
  packageName: "System.Security",
  restored: true,
});
```

## AI Coding Instructions

- Treat `System.Security` as a project-level NuGet dependency, not a TypeScript runtime package.
- Keep package reference changes in `Pams.Data.csproj` so restore and build tooling can resolve the dependency.
- Verify package restore succeeds before diagnosing missing security-related .NET types.
- Avoid adding client-side code that assumes `System.Security` can be imported from JavaScript or TypeScript.
