Add Cuckoo Catfish Optimizer (CCO)

[karahanballi]

Description

This pull request adds the Cuckoo Catfish Optimizer (CCO) to the Mealpy library under the swarm_based module.

The implementation follows the original algorithm design while fully complying with Mealpy’s optimizer interface. It relies on the internal random generator for reproducibility, uses built-in boundary correction, and applies min/max-safe greedy selection. A lightweight pytest-based smoke test is included to validate basic functionality.

Changes

• Added OriginalCCO implementation in mealpy/swarm_based/CCO.py
• Registered CCO in mealpy/__init__.py
• Added basic unit test for CCO (tests/swarm_based/test_CCO.py)

✅ Checks

• Code style follows the project conventions
• Tests passed locally (python -m pytest -q tests/swarm_based/test_CCO.py)

ℹ Additional Information

• Lévy flight is implemented using Mantegna’s method with NumPy only
