- Remove outdated ResourceAnalogy, RequestStructureDemo, and VersioningStrategyDemo

docs(api-design): completely rewrite API design chapter with restaurant analogy
- Add clear problem scenarios and solutions
- Include practical e-commerce API examples
- Add terminology glossary
- Improve error handling and versioning sections

style(ai-history): enhance FoundationDemo with better visual hierarchy
