NuGet package dependency

Hangfire.Core is a NuGet package dependency declared by `Pams.Business.csproj`. It supplies background job scheduling APIs for .NET code in the Pams business layer and requires a configured Hangfire storage and worker process at runtime.

## Usage

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

const projectFile = "Pams/Logic/Pams.Business/Pams.Business.csproj";

execFileSync("nuget", ["restore", projectFile], {
  stdio: "inherit",
});
```

## AI Coding Instructions

- Keep `Hangfire.Core` declared through the existing NuGet dependency mechanism in `Pams.Business.csproj`.
- Configure Hangfire storage and worker startup outside this package reference before scheduling jobs.
- Do not assume JavaScript code can call Hangfire directly; enqueue jobs from the .NET business layer.
- Check the project’s existing package format before changing package references or restore commands.
