Release MLX Knife 1.0.3 - GitHub Issues Implementation & Enhanced User Experience

Community-driven feature development implementing key GitHub Issues:
    - Fix Issue #7: Health check consistency for fuzzy model names - unified health check logic ensures
  identical status regardless of name format (Phi-3 vs mlx-community/Phi-3-mini-4k-instruct-4bit)
    - Add Issue #6: Repository name validation - pre-validation for HuggingFace Hub 96-character limit with
  clear error messages
    - Add Issue #13: Hash-based disambiguation - use commit hashes to resolve ambiguous model names (mlxk show
  Llama@de2dfaf5 → mlx-community/Llama-3.3-70B-Instruct-4bit)

  Enhanced user experience:
    - Pure local hash resolution without external API calls, offline-capable
    - Improved model name disambiguation logic for better workflow
    - Real user workflow support - see hashes in mlxk list, use directly in other commands
