- Add GearSix icon ('gear-six') to icon registry — was missing, causing
Config type to show FileText fallback instead of its configured icon
- Add 'gray' to ACCENT_COLORS palette with CSS variables — was missing,
causing Config type color to fall back to muted foreground
- Extract sidebar section logic to utils/sidebarSections.ts for testability
- Add Config type + instance to mock entries for browser dev mode
- Add tests: icon resolution, gray color, sidebar section builder
