M8: a double-click on a layer's icon zooms to it, as in Figma

Measured in Figma's web app on 2026-11-12: a double-click on a layer's icon in the Layers panel zooms the canvas to the layer and starts no rename; a double-click on the name renames. The row now checks whether the double-click fell within the rect it paints the icon in, and if so selects the layer and runs view.zoomSelection. A double-click elsewhere on the row is unchanged.

It sampled a 1x1 render without the canvas's magnified-image pixels, so on an image magnified past 2x it blended a 1 px line with its neighbours (#3D444D picked as #343B44 beside #151B23), and the pixel it sampled began at the pointer instead of being centred on it. It now matches the canvas when zoomed in; zoomed out it still samples the full-resolution image, not the smaller copy the canvas may show. Test: `eyedropper_image_tests` |
