feat(dataset): handle image data in LLM cleaning

Updates pre-commit hooks.

Previously, the cleaning pipeline was entirely disabled for datasets

containing image messages.

Image conversations now receive a default score, bypassing text-focused

LLM cleaning. This enables partial cleaning for mixed datasets and

prevents pipeline failures.
