refactor: restructure codebase into modular architecture
- Split monolithic app.py (400+ lines) into organized modules - Extract models, forms, and commands into separate files - Implement Flask blueprints for route organization - Maintain full functionality with cleaner architecture - Update all templates to use new blueprint URLs - Enhance README with technical documentation Structure: ├── app.py (50 lines) - Flask app factory ├── models.py (62 lines) - SQLAlchemy models ├── forms.py (43 lines) - WTForms definitions ├── commands.py (74 lines) - CLI commands └── routes/ - Blueprint modules for each feature 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <noreply@anthropic.com>
