design: finalize logo and update Pastel to palette icon

Logo Updates:
- Using authentic Lucide brush and wrench icons
- Wrench vertical, brush horizontal (90° rotation)
- Aligned bottom edges for visual balance
- Scaled up to 5x for better visibility
- Removed center dot for cleaner look

Pastel Icon:
- Changed from paintbrush to proper palette icon
- Palette with thumb hole and color dots
- Better represents color manipulation tool

Visual improvements:
- Clean, professional crossed tools design
- Proper alignment and spacing
- Large, visible icons at all sizes
- Consistent with Lucide icon library
