BESSER Generator Operations

Every BESSER generator implements the same shape:

class GeneratorInterface(ABC):
    def __init__(self, model, output_dir=None): ...
    def generate(self): ...

If output_dir is omitted, output goes to <cwd>/output/. The directory is created automatically (os.makedirs(..., exist_ok=True)).

Regeneration always overwrites. Every call to generate() replaces the output files entirely. This is by design — the model is the source of truth. Customizations belong in separate files (see "Safe customization" below).
