ExitCodeGenerator class abstract interface

Strategy interface for determining the exit code returned from a JetLeaf application or a process.

This is typically used when the application is shutting down due to an error, and a custom exit code should be returned to the operating system.

Classes implementing this interface can be plugged into the JetLeaf runtime, allowing them to determine a meaningful exit code based on the state of the application or the error encountered.

Example:

class MyExitCodeGenerator implements ExitCodeGenerator {
  @override
  int getExitCode() {
    // Return 1 to indicate error
    return 1;
  }

  @override
  String getPackageName() => "test";
}

You can register this generator during the application context setup or inside an error-handling pipeline.
