fix: gracefully handle processor load failures for multimodal models (#82)

[umran666]

Catches configuration/dependency load failures when initializing a multimodal model's processor, logging a warning rather than crashing the model initialization loop. This allows multimodal models to be abliterated on text-only pipelines even if optional vision dependencies (such as torchvision) are missing.

Code Review

This pull request wraps the initialization of the multimodal processor in a try-except block to handle loading failures gracefully with a warning. The reviewer recommended catching specific exceptions rather than a broad Exception to prevent masking other programming errors.
