feat: add CSS Animation Editor tool

Comprehensive visual editor for CSS @keyframe animations:
- AnimationSettings: name, duration, delay, easing (incl. cubic-bezier), iteration, direction, fill-mode
- KeyframeTimeline: drag-to-reposition keyframe markers, click-track to add, delete selected
- KeyframeProperties: per-keyframe transform (translate/rotate/scale/skew), opacity, background-color, border-radius, blur, brightness via sliders
- AnimationPreview: live preview on box/circle/text element with play/pause/restart and speed control (0.25×–2×)
- PresetLibrary: 22 presets across Entrance/Exit/Attention/Special categories with animated thumbnails
- ExportPanel: plain CSS and Tailwind v4 @utility formats with copy and download
