Update documentation for first-time users and fix outdated agent names

Major documentation improvements:
- Fixed all outdated agent names throughout README.md and GETTING_STARTED.md
- Updated agent references from old names (todo-keeper, changelog-keeper, setup-repository)
  to new names (keepaTodofile, keepaChangelog, setupRepository)
- Created comprehensive HELLO_WORLD_TUTORIAL.md with step-by-step guide for new users
- Added prominent tutorial links in README.md and GETTING_STARTED.md for better discoverability
- Updated Python version requirements from 3.8 to 3.9 in project templates
- Enhanced first-time user experience with clear guidance and working examples

Documentation now provides:
✅ Working commands that match actual agent names
✅ Clear separation between new users and experienced users
✅ Complete tutorial from installation to running code
✅ Proper guidance for scenario one (greenfield projects)

+# Hello World Tutorial - Your First Kaizen Agentic Project
+
+This step-by-step tutorial will guide you through creating your first project with Kaizen Agentic agents. By the end, you'll have a working Python project with tests, code quality tools, and AI agents to help with development.
+
+## Prerequisites
+
+- Python 3.8 or higher
+- Basic knowledge of command line
+
+## Step 1: Install Kaizen Agentic
+
+```bash
+pip install kaizen-agentic
+```
+
+Verify the installation:
+
+```bash
+kaizen-agentic --version
+kaizen-agentic list
+```
+
+You should see a list of available agents.
+
+## Step 2: Create Your First Project
+
+```bash
+# Create a new project called "hello-world"
+kaizen-agentic init hello-world --template python-basic
+
+# Navigate to the project
+cd hello-world
+```
+
+**What just happened?**
+- Created a complete Python project structure
+- Installed 3 essential agents: setupRepository, keepaTodofile, keepaChangelog
+- Generated Makefile with development commands
+- Set up pyproject.toml with modern Python configuration
+- Created README.md with project documentation
+
+## Step 3: Set Up Development Environment
+
+```bash
+# Set up virtual environment and install dependencies
+make setup-complete
+```
+
+This command:
+- Creates a Python virtual environment (`.venv/`)
+- Installs development tools (pytest, black, flake8, mypy)
+- Sets up the project for development
+
+## Step 4: Explore Your Project Structure
+
+```bash
+# See what was created
+ls -la
+
+# Check the available make commands
+make help
+```
+
+Your project now has:
+```
+hello-world/
+├── src/hello_world/          # Your Python package
+├── tests/                    # Test files
+├── agents/                   # AI agents for development help
+├── docs/                     # Documentation
+├── Makefile                  # Development commands
+├── pyproject.toml           # Python project configuration
+├── README.md                # Project documentation
+└── CLAUDE.md                # Agent configuration for Claude Code
+```
+
+## Step 5: Create Your First Function
+
+Create a simple "Hello World" module:
+
+```bash
+# Create the main hello.py file
+cat > src/hello_world/hello.py << 'EOF'
+def hello_world() -> str:
+    """Return a friendly greeting."""
+    return "Hello, World!"
+
+
+def main() -> None:
+    """Main entry point."""
+    print(hello_world())
+
+
+if __name__ == "__main__":
+    main()
+EOF
+```
+
+## Step 6: Write Your First Test
+
+```bash
+# Create a test file
+cat > tests/test_hello.py << 'EOF'
+def test_hello_world():
+    """Test the hello_world function."""
+    from hello_world.hello import hello_world
+    assert hello_world() == "Hello, World!"
+
+
+def test_main_function_exists():
+    """Test that main function exists."""
+    from hello_world.hello import main
+    # Just check it's callable
+    assert callable(main)
+EOF
+```
+
+## Step 7: Run Your Tests
+
+```bash
+make test
+```
+
+You should see:
+```
+============================= test session starts ==============================
+...
+tests/test_hello.py::test_hello_world PASSED                              [100%]
+tests/test_hello.py::test_main_function_exists PASSED                     [100%]
+
+============================== 2 passed in 0.02s
+```
+
+## Step 8: Check Code Quality
+
+```bash
+# Check code formatting and style
+make lint
+
+# Auto-format your code
+make format
+
+# Run lint again to see improvements
+make lint
+```
+
+## Step 9: Run Your Program
+
+```bash
+# Activate virtual environment
+source .venv/bin/activate
+
+# Run your hello world program
+python src/hello_world/hello.py
+```
+
+You should see: `Hello, World!`
+
+## Step 10: Explore AI Agents
+
+Your project includes helpful AI agents:
+
+```bash
+# See installed agents (when kaizen-agentic is available)
+ls agents/
+
+# View agent documentation
+cat agents/agent-keepaTodofile.md
+```
+
+**What do these agents do?**
+- **setupRepository**: Helps set up Python projects following best practices
+- **keepaTodofile**: Manages TODO.md files for task tracking
+- **keepaChangelog**: Maintains CHANGELOG.md files for version history
+
+## Step 11: Development Workflow
+
+Your typical development workflow is now:
+
+```bash
+# 1. Write code
+vim src/hello_world/my_feature.py
+
+# 2. Write tests
+vim tests/test_my_feature.py
+
+# 3. Run tests
+make test
+
+# 4. Check code quality
+make lint
+
+# 5. Format code if needed
+make format
+
+# 6. Commit changes
+git add .
+git commit -m "Add my new feature"
+```
+
+## Step 12: Add More Agents (Optional)
+
+As your project grows, add more specialized agents:
+
+```bash
+# Add TDD workflow agent
+kaizen-agentic install tdd-workflow
+
+# Add code refactoring agent
+kaizen-agentic install code-refactoring
+
+# Check what's installed
+kaizen-agentic status
+```
+
+## Next Steps
+
+🎉 **Congratulations!** You've created your first Kaizen Agentic project.
+
+**Continue learning:**
+
+1. **Read the docs**: Check out [GETTING_STARTED.md](GETTING_STARTED.md) for more advanced usage
+2. **Try different templates**: Explore `python-web`, `python-cli`, or `python-data` templates
+3. **Use with Claude Code**: The agents work seamlessly with Claude Code for AI-assisted development
+4. **Customize**: Modify the Makefile and pyproject.toml to fit your needs
+
+**Common next steps:**
+- Add a CLI interface using `click` or `argparse`
+- Set up GitHub Actions for CI/CD
+- Add more comprehensive tests
+- Create documentation with Sphinx
+- Package and publish to PyPI
+
+## Troubleshooting
+
+**"kaizen-agentic: command not found"**
+```bash
+pip install kaizen-agentic
+```
+
+**"make: command not found"**
+- On Windows: Install `make` via chocolatey or use the commands directly
+- On macOS: Install via `brew install make`
+- Alternative: Run commands directly (see Makefile for exact commands)
+
+**Virtual environment issues**
+```bash
+# Remove and recreate
+rm -rf .venv
+make setup-python
+```
+
+**Import errors in tests**
+```bash
+# Make sure you're in the project root and virtual env is activated
+source .venv/bin/activate
+make test
+```
