Updated link_model() and verify_model_links() functions to:
- Extract target directory directly from dest path (e.g., "checkpoints/model.safetensors")
- Remove model_type parameter from function signatures
- Support multiple target directories per model when files go to different locations
- Simplified function calls throughout the script
Also added bin/ directory to .gitignore allowlist to track utility scripts.
This change complements the models_huggingface.yaml refactoring that embedded
the type directory in the dest paths.
