研究方向
The issue requests adding `createConicGradient` to node canvas, matching the browser API. The implementation should follow the pattern of existing gradient methods like `createLinearGradient` and `createRadialGradient`. Look at the source file `lib/canvas.js` and the native binding code (likely `src/Canvas.cc` or similar) to understand how gradients are created. The Cairo library supports conic gradients via `cairo pattern create conical`. No linked PRs or comments exist; the work is entirely new and unassigned.
