Build me a .NET 10 batch execution system for SQL Server that can run jobs by JobId, execute steps in order, and keep going with retry handling when something fails. I want it to save every job and step execution so I can see what happened later, and I want a way to re run only the failed steps without losing the successful history.

Please include clear operational logging with Serilog, support for retry with backoff, and a clean separation between the core job logic, the application flow, and the database or logging code. It should use SQL directly, not an ORM, and be set up so I can run it from a console app and also have a place for a web app if needed later. If you need current .NET or SQL Server details, look them up online and use the latest recommended approach.
