feat(tools): implement advanced brush tools - Clone Stamp, Smudge, and Dodge/Burn
Added three professional-grade image manipulation tools to complete Feature 4:
Clone Stamp Tool (Shortcut: 8)
- Sample from source location with Alt+Click
- Paint sampled content to destination
- Maintains relative offset for natural cloning
- Supports soft/hard brush with hardness setting
Smudge Tool (Shortcut: 9)
- Creates realistic paint-smearing effects
- Progressively blends colors for natural smudging
- Uses flow setting to control smudge strength
- Soft brush falloff for smooth blending
Dodge/Burn Tool (Shortcut: 0)
- Dodge mode: Lightens image areas (default)
- Burn mode: Darkens image areas (Alt key)
- Professional photography exposure adjustment
- Respects hardness setting for precise control
All tools:
- Fully integrated with tool palette and keyboard shortcuts
- Support smooth interpolation for fluid strokes
- Use existing tool settings (size, opacity, hardness, flow, spacing)
- Lazy-loaded via code splitting system
- Icons from Lucide React (Stamp, Droplet, Sun)
