Implement hybrid agent distribution system

Complete implementation of the agent distribution framework including:

CORE INFRASTRUCTURE:
- AgentRegistry: Agent discovery, categorization, and dependency management
- AgentInstaller: Agent installation, updates, and removal with safety measures
- ProjectInitializer: Template-based project initialization with agent integration
- CLI Tool: Comprehensive kaizen-agentic command-line interface

DISTRIBUTION FEATURES:
- Python package distribution with console script entry point
- Agent categorization (project-management, development-process, code-quality, etc.)
- Project templates (python-basic, python-web, python-cli, python-data, comprehensive)
- Dependency resolution and validation
- Idempotent operations with backup and rollback support

CLI COMMANDS:
- kaizen-agentic init: Initialize new projects with agents
- kaizen-agentic install/update/remove: Manage agents in existing projects
- kaizen-agentic list/status/validate: Discovery and maintenance
- kaizen-agentic templates: Project template management

INTEGRATION & DOCUMENTATION:
- Makefile targets for agent management (list-agents, update-agents, etc.)
- Automatic Claude Code configuration updates (CLAUDE.md)
- Comprehensive documentation (GETTING_STARTED, AGENT_DISTRIBUTION, CLI_CHEAT_SHEET)
- Multi-language build system integration examples
- Complete test coverage for all components

PACKAGE STRUCTURE:
- Console script: kaizen-agentic command available globally
- Package data: All agents included for distribution
- Dependencies: click, pyyaml for CLI and parsing
- Testing: Comprehensive test suite for registry and installer

This enables sharing specialized AI agents across projects with easy installation,
updates, and management through both CLI and integrated Makefile targets.
