feat(phase2): implement ManualCropUI with drag handles
- useCropHandles.ts: Hook managing crop bounds state, drag operations, and constraints - 8 draggable handles (4 corners + 4 edges) - Real-time crop bounds calculation during drag - Constrained within image bounds (no dragging outside) - Minimum crop size enforcement (100x100px) - Support for mobile (touch) and desktop (mouse) events - Bounds validation on initialization - ManualCropUI.tsx: Interactive crop preview component - Responsive image display with calculated scaling - Semi-transparent overlay outside crop box with visible bounding box - 8 draggable handles with visual feedback (highlight/scale on hover) - 'Use Full Photo' button to clear crop and show full image - Real-time onCropChange callbacks to parent - Error handling for failed image loads - Touch and mouse event support (desktop + mobile) - TypeScript strict mode compliant - Tests: 26 comprehensive test cases - Hook tests (26 passing): initialization, setCrop, resetCrop, drag operations (corners, edges), constraints, endDrag, edge cases - Component tests (26 passing): rendering, handles, overlay, callbacks, button, error handling, dimensions, touch/mouse support, responsive behavior, size enforcement, bounds display All 364 tests passing (13 test files, zero regressions) Minimum crop size: 100x100px Handle visual feedback on hover/drag TypeScript strict mode: ✓
