What Changed

### 1. Priority System
- Types: Added `IdeaPriority` type (`low` | `medium` | `high` | `urgent`) with color-coded config
- IdeaCard: Colored left border strip indicates priority (gray/blue/orange/red)
- NewIdeaSheet: 4-button priority picker with color highlights and icons
- Search: Priority boost in scoring — urgent/high ideas rank higher
- Sort: Ideas sorted by priority first, then by date
- Widget: Priority dots shown next to recent ideas (colored circles)

### 2. Categories System
- Types: Added `IdeaCategory` type with 6 categories: inbox, project, personal, work, creative, research
- HomeScreen: Horizontal scrolling category tabs above sync filter chips
- NewIdeaSheet: Grid-style category selector with icons
- IdeaCard: Category badge shown below text (except 'inbox' which is default)
- Search: Category filter parameter integrated into `searchIdeas()`
- Widget: Category icons displayed next to recent ideas

### 3. Swipe Actions on IdeaCard
- PanResponder for native gesture handling (no external libs)
- Swipe left → red "Delete" background revealed → delete confirmation
- Swipe right → blue "Edit" background → enters edit mode
- `SWIPE_THRESHOLD` = 80px, with spring animation snap-back
- Background action indicators visible during swipe

### 4. Fuzzy Search
- New file: `src/utils/fuzzySearch.ts`
- Levenshtein distance algorithm for fuzzy matching
- `fuzzyScore()` returns 0-1 score (exact → contains → prefix → distance)
- `findMatchRanges()` returns highlight ranges for UI
- `debounce()` utility for search input (300ms)
- Search results now show highlighted matched text

### 5. Statistics Dashboard
- New file: `src/components/StatsCard.tsx`
- Collapsible card at top of HomeScreen
- Compact row: total ideas, this week count, urgent count (animated counters)
- Expanded view: priority bar chart, category breakdown, top tags
- `LayoutAnimation` for smooth expand/collapse transitions
- `AnimatedCount` component with eased count-up animation

### 6. iOS Widget Enhancements
- Priority indicators: Colored dots next to each recent idea
- Category icons: Emoji icons for idea categories
- Quick Voice button: New `QuickVoiceCaptureIntent` opens app in voice mode
- Lock screen: Priority dots in accessoryRectangular widget
- WidgetBridge: Now passes priority + category data to widget JSON

### 7. Data Migration
- Both `useIdeaVault` and `useSyncedIdeaVault` auto-migrate existing data
- Missing `priority` defaults to `'medium'`
- Missing `category` defaults to `'inbox'`
- All new fields are optional — zero breaking changes to stored data

## No External Dependencies Added
All features implemented using React Native core APIs + Expo SDK built-ins.

## Known Limitations
- Haptic feedback (expo-haptics) not added to keep zero new deps — can add in Gen 7
- Background fetch (expo-background-fetch) deferred — AppState-based sync is sufficient
- Fuzzy search debounce not wired into SearchBar component (debounce utility ready for Gen 7)
