xfy aadfed2595 test(lightbox): add happy-dom behavior regression tests for refactor
为现代化重构(var→const、拆 IIFE、for→for..of)补行为回归防线。
黑盒驱动 window.__initLightbox,覆盖高风险路径:
- 循环闭包捕获 idx(点第 1/2/3 张 counter 显示正确序号)
- 点击打开(overlay 创建、origSrc 去 query、caption、单张 counter 隐藏)
- 关闭(Esc / 点背景;点图片本身不关)
- 图集 gotoIndex 循环边界(首末衔接 + originNode 更新后焦点归还)
- 单张图不参与切换

happy-dom 20.10.6 作 devDep,vitest 默认环境改 happy-dom;
geometry.test.ts 用 // @vitest-environment node 指令保持纯函数在 node 跑。

23 tests (12 geometry + 11 behavior) 全绿。
