feat: implement palette generation features
Add complete palette generation system with multiple methods:
**New Components:**
- ColorSwatch component - Individual color display
- Click to copy to clipboard
- Hover effects with copy icon
- Configurable sizes (sm, md, lg)
- Optional color label display
- Check icon on successful copy
- PaletteGrid component - Grid display for color palettes
- Responsive grid layout (3-6 columns)
- Click handler for color selection
- Empty state message
- Flexible and reusable
- Select component - Dropdown selector
- Consistent styling with other inputs
- Optional label support
- Keyboard accessible
- Focus ring styling
**Palette Pages:**
1. Gradient Creator (/palettes/gradient)
- Multiple color stop editor (add/remove)
- Configurable step count (2-1000)
- Color space selection (RGB, HSL, Lab, LCH, OkLab, OkLCH)
- Live gradient preview bar
- Full palette grid display
- Interactive color pickers for each stop
- Real-time generation
2. Distinct Colors (/palettes/distinct)
- Count selector (2-100 colors)
- Distance metric selection (CIE76, CIEDE2000)
- Simulated annealing algorithm
- Statistics display:
- Minimum distance
- Average distance
- Generation time
- Loading state with progress message
- Quality metrics for generated palette
3. Palettes Dashboard (/palettes)
- Overview of all palette generators
- Feature cards with icons
- "Coming Soon" badge for harmony palettes
- Quick navigation to each generator
- Feature highlights for each method
**Features:**
- All palette generators integrated with Pastel API
- Toast notifications for success/error
- Loading states during generation
- Copy colors to clipboard
- Responsive layouts
- Empty states
- Error handling
**API Integration:**
- useGenerateGradient mutation
- useGenerateDistinct mutation
- Proper error handling and loading states
- Result caching with React Query
Build successful! 3 new palette pages rendering.
Next: Harmony palettes, accessibility tools, and named colors.
