This PR represents a comprehensive architectural refactor aimed at modernizing the repository. The goal was to transition from legacy Python patterns to a production-ready, type-safe, and automated environment using the latest features of Python 3.12.

🛠 Key Engineering Changes
Strict Type Hinting: Integrated typing.Protocol, Self, Generics, and TypeVar across 20+ design patterns to ensure structural typing and better IDE support.

Advanced Pattern Implementation: - Updated Flyweight using weakref.WeakValueDictionary for professional memory management.

Modernized Memento with dataclasses(frozen=True) for state immutability.

Refactored State and Composite using abc.ABC for formal interface contracts.

CI/CD Pipeline: Added a GitHub Actions workflow (tests.yml) to automate testing on every push and pull request.

Quality Assurance: - Integrated Ruff as the primary linter for high-performance code analysis.

Added a Pytest suite in /tests to validate core pattern logic.

Configured pre-commit hooks to maintain code consistency.

📈 Impact
These changes significantly improve the Developer Experience (DX), making the repository not just an educational resource, but a benchmark for how modern Python software should be architected.

✅ Checklist
[x] Code adheres to PEP 484 and PEP 585.

[x] All core patterns have been refactored.

[x] Tests are passing locally.

[x] Linting (Ruff) and Type Checking (Mypy) pass without errors.
