Add periodic table visualization and URL hash tracking

- Replace subway map with periodic table of commands
- Info panel shows command details on hover
- Click element to jump to command in Commands section
- URL hash updates as you scroll between sections
- Direct linking to sections works
- Fix spacing issues in solution section
