🛡️ Critical Fixes & Modernization

• Memory Safety: Replaced unsafe f.read() (which crashes on large files) with efficient line-by-line streaming.
• Architecture: Refactored the entire codebase from a flat script to a modular ProjectAnalyzer class using modern pathlib.
• Standardization:
  • Renamed the script to main.py.
  • Standardized CLI arguments (e.g., used -d for directory).
