Phase 3: Graph View, Backlinks UI, Quick Switcher, Dark Mode, Export
Features: - GraphView.vue: SVG-based force-directed graph visualization for projects - QuickSwitcher.vue: Cmd+K modal with fuzzy search via /search API - Dark Mode: Theme toggle in Header, persisted in localStorage, system pref support - Backlinks UI: Incoming and outgoing links in DocumentView - Export: Document (markdown/JSON) and Project (ZIP/JSON) export with download - New composables: useTheme.ts for dark/light/system theme management - New store methods: fetchBacklinks, fetchOutgoingLinks, search, exportDocument, fetchProjectGraph, exportProject - TypeScript types for all Phase 3 API responses
