Add background execution option to RunCommand

This commit introduces a new boolean option `--background` (or `-b`) in the `RunCommand` to allow commands to run asynchronously. The `RunCommandOptions` class now includes a `Background` property to track this setting. Additionally, the `RunCommandOptionsHandler` has been updated to conditionally handle process output and error data based on the background execution state.
