feat: add How It Works documentation page

- Create comprehensive /how-it-works page explaining TPMJS architecture
- Add detailed sections on developer workflow, AI agent integration, and system internals
- Include quality scoring formula, health checks, and data flow diagrams
- Add navigation link to AppHeader between Tools and Playground
- Style consistently with existing pages (Publish, Playground)
- Fix: remove debug console.log from ToolsSidebar
