feat: implement a very flexible runner for "pre" and "post" scripts
This new functionality now makes it possible to execute scripts at the start or end of the build process, while also being super simple to expand to add further script stages in the future. It also supports effortless reuse of scripts for multiple stages, since the scripts are now executed with the "current stage" as their 1st argument, to allow them to easily determine which stage they're running in.

### Custom build scripts
|
||||
|

If you want to execute custom shell script or commands in the image build, you shouldn't edit `build.sh` or the `Containerfile` directly. Instead, you can create a shell script in the `scripts/` directory (look at the `example.sh`). After creating your script, enable it in the `scripts:` section of your `recipe.yml`.

Instead, you can create shell scripts in the `scripts/` directory (look at the `example.sh`). After creating your scripts, enable them in the `scripts:` section of your `recipe.yml`, within the specific "build stage" category where the scripts are intended to be executed.
|

|
||||
Your scripts will be given exactly one argument when they are executed, which specifies its precise execution phase and corresponds to the name of the `scripts:` category that it was assigned to. The primary purpose of this argument is to streamline the reuse of scripts for multiple stages.
