fix: edge anchor clamping, transition NaN guard, PPTX aspect ratio
- Diagrams: nearestEdgeAnchor clamps to actual point coordinates, not center (#562)
- Slides: createTransition guards against NaN/Infinity duration (#560)
- Slides: PPTX normalizePosition uses uniform scaling to preserve aspect ratio (#563)
