NuGet package dependency

`Pams.Data.csproj` defines NuGet package dependencies for the Pams.Data project. During package restore and build, it supplies the assemblies required by the data-layer code and records dependency versions in the project configuration.

## Usage

```ts
import { readFile } from "node:fs/promises";

const projectFile = "Pams/Data/Pams.Data/Pams.Data.csproj";
const projectXml = await readFile(projectFile, "utf8");

const packageReferences = [
  ...projectXml.matchAll(
    /<PackageReference\s+Include="([^"]+)"(?:\s+Version="([^"]+)")?/g,
  ),
].map((match) => ({
  name: match[1],
  version: match[2] ?? "version defined elsewhere",
}));

console.log(packageReferences);
```

## AI Coding Instructions

- Keep package dependency changes in `Pams.Data.csproj` aligned with the dependency format already used by the project.
- Verify package restore after changing dependency declarations or versions.
- Avoid adding data-access dependencies to unrelated projects when the dependency belongs in `Pams.Data`.
- Check for version conflicts with packages referenced by other Pams projects.
