Add complete Kaizen Agentic framework foundation

- Essential project files: .gitignore, pyproject.toml, README.md
- Documentation framework: CHANGELOG.md, CONTRIBUTING.md, TODO.md, CLAUDE.md
- 15 specialized agent definitions for comprehensive development workflow
- Core source code structure with optimization framework
- Testing infrastructure with example tests
- Proper Python package structure following PythonVibes standards

This establishes the complete foundation for the AI agent development framework
with agent-driven workflows, continuous improvement principles, and comprehensive
development infrastructure.
