refactor: reorganize examples for better clarity

- Simplify quick_start.py to just basic examples (~45 lines)
- Move tools example to dedicated using_tools.py file
- Move MCP configuration example to mcp_servers.py file
- No new content added - just reorganized existing examples

This makes the quick start truly quick and provides dedicated
files for users who need specific advanced features.
