Release MLX Knife 1.0-rc2: Enhanced Memory Management & Exception Safety

Browse Source 
**Key Improvements**
  - Robust exception handling during model loading with guaranteed cleanup
  - Protection against nested context manager usage in MLXRunner
  - Safe cleanup that handles partial loading failures gracefully
  - Exception-resilient cache clearing operations
  - Safe tokenizer attribute access with proper defaults
  - Graceful memory statistics handling when metrics unavailable
  - Comprehensive unit test coverage for memory management edge cases

 **Changes**
  - Updated version to 1.0-rc2 across all documentation files
  - Enhanced MLXRunner context manager with bulletproof exception safety
  - Added comprehensive unit tests for memory management scenarios
  - Improved error handling for partial model loading failures
  - Updated test coverage documentation (96/96 tests passing)
  - Refined README to focus on key features rather than test metrics

  This release focuses on production-ready memory management and exception
  safety, making MLX Knife more robust for real-world usage scenarios.
