修复svg2pptx转换器多项bug + 新增管线兼容性文档

svg2pptx.py:
- 修复image opacity不生效(通过OOXML alphaModFix)
- 修复环形图stroke渐变url(#id)引用不支持(fallback第一个stop颜色)
- 修复viewBox内缩放不传递(g组scale累积到所有子元素)
- 修复text baseline偏移(区分text-after-edge和auto)
- 修复text-anchor:middle/end的x坐标偏移
- 添加--html-dir参数支持

html2svg.py:
- 修复图片相对路径解析(以HTML文件所在目录为基准)
- 新增3种CSS兜底预处理(background-clip:text、text-fill-color、mask-image)

新增 references/pipeline-compat.md:
- HTML->SVG->PPTX管线兼容性规则文档
- CSS禁止清单、防偏移写法指南、防偏移checklist
- 已整合到SKILL.md和prompts.md中引用

prompts.md:
- 新增内联SVG防偏移约束(禁SVG text、用HTML叠加)

示例产物:
- ppt-output/ 包含SU7示例的完整HTML/SVG/PPTX产物
