Major improvements to UI state management and user preferences: - Add theme toggle with dark/light mode support - Implement Zustand persist middleware for UI state - Add ui-store for panel layout preferences (dock width, heights, tabs) - Persist tool settings (active tool, size, opacity, hardness, etc.) - Persist canvas view preferences (grid, rulers, snap-to-grid) - Persist shape tool settings - Persist collapsible section states - Fix canvas coordinate transformation for centered rendering - Constrain checkerboard and grid to canvas bounds - Add icons to all tab buttons and collapsible sections - Restructure panel-dock to use persisted state Storage impact: ~3.5KB total across all preferences Storage keys: tool-storage, canvas-view-storage, shape-storage, ui-storage 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
