fix(canvas): improve Figma mask and text fidelity

CHANGELOG.md

 - Fix MCP startup in the browser.
 - Fix CanvasKit loading outside the browser when project paths contain spaces.
 - Render imported Figma layer and fill blend modes such as multiply, screen, overlay, difference, hue, saturation, color, and luminosity.
-- Render common imported Figma mask stacks so visible layers above alpha, vector, or luminance masks are clipped by the mask shape.
+- Render common imported Figma mask stacks so visible layers above alpha, vector, or luminance masks are clipped by the mask shape, including consecutive mask layers.
 - Render Figma-style smoothed rectangle corners, including independent corner radii, and effect blend modes from imported Figma files.
 - Improve imported tiled image fills by applying Figma image transforms when repeating image patterns.
+- Keep imported Figma boolean operations editable as boolean-operation nodes instead of flattening them to vectors.
+- Apply imported variable font axes from Figma `fontVariations` when rendering text.

 ## Highest-priority visual gaps
 
 These are parsed or visible in Figma docs and most likely to cause visible differences in real design files:
 
-1. **Masks** — tune multi-mask stacks and exact Figma edge cases beyond the common alpha/vector/luminance path.
+1. **Masks** — tune remaining exact Figma stack semantics beyond common alpha/vector/luminance and consecutive-mask paths.
 2. **Corner smoothing** — expand Figma fixture comparisons and tune remaining stroke/effect edge cases.
 3. **Pattern fills/strokes** — support Figma pattern paint objects and transforms beyond image tile fills.
-4. **Font variations** — apply variable-font axes from imported Figma metadata.
+4. **Variable-font fixtures** — broaden real-file coverage for variable axes and OpenType feature metadata.
-5. **Boolean operation import** — keep Figma `BOOLEAN_OPERATION` nodes as boolean operations where possible instead of importing them as vectors.
+5. **Boolean operation editing** — improve inspector/tooling workflows for imported boolean-operation nodes.
 6. **Layout grids and guides** — render/edit page guides and Figma layout grids, or clearly keep them round-trip-only.
 7. **Full component property and slot workflows** — support authoring, not just preserving imported payloads.
 8. **Prototype metadata** — start by preserving prototype flows/connections even before building playback.
