- webfont-sdk: 新增 Node 模式（node-registry），GlobalFonts 注册 + 每 chunk 唯一 family + 逗号链回退 - leafer-x-webfont: fontFamily 链写回（Node 端），scan 链归一化防套娃、rewriteFamily 跳过链形态防抹回 - 修复 pnpm 双实例 bug: @napi-rs/canvas 版本对齐 1.0.6（根与 SDK 同版本共享 .pnpm 条目） - 基准测试重构: 用例表抽取为 基准测试用例.ts 共享，SSIM 计算收敛到 scripts/ssim.ts - 新增 基准测试_leafer.test.ts: @leafer-ui/node + Skia 渲染验证（无浏览器），ttf 输出用例 SSIM=1.0000；woff2 用例仅计时（Skia 不吃 woff2，容器验证由 puppeteer 版守护） - Node 端集成测试 scripts/test-leafer-node.mts（插件链路 SSIM=1.0000）
