feat: VBA Automated Testing and Precise Error Reporting System

Implement a comprehensive VBA testing framework that provides precise
line-by-line error reporting through code weaving technology.

Core Features:
- CodeWeaver: Injects line number labels and error handling into VBA code
- LoggerInjector: Manages TestLogger module for capturing test results
- TestRunner: Orchestrates Excel lifecycle and test execution
- Command-line interface supporting single and batch testing

Key Capabilities:
- Captures exact line numbers where errors occur
- Displays source code context for error locations
- Non-invasive testing (original files unchanged)
- Batch testing support with detailed summaries

Components:
- vba_test_runner.py: Main framework implementation
- demo.xlsm: Demo Excel file with test procedures
- create_demo.py: Script to generate demo files
- check_vba_access.py: VBA access permission checker
