v2.0.1 - Robust Rendering for New Digital Invoices (Full-Tax Stamps Support)

🚀 What's New / 更新内容

• Fix: Invoice Stamp Loss: Completely resolved the issue where electronic stamps and icons would disappear after merging, especially for the latest Full-Digital Electronic Invoices.
• 修复：发票印章丢失：彻底解决了合并后红色监制章、发票章消失的问题，完美支持最新的全电发票（数字化电子发票）。
• High-Definition Rendering: Switched to a high-resolution rasterization rendering logic (3.0x zoom / ~216 DPI) to ensure 100% visual fidelity for financial reimbursement.
• 高清渲染技术：引入高清位图渲染逻辑（3.0 倍率 / 约 216 DPI），确保 100% 视觉还原，满足财务报销打印的清晰度要求。
• Layout Optimization: Refined A4 coordinate calculations with added safety margins to prevent content from being clipped by printers.
  排版逻辑优化：精细化 A4 页面坐标计算，增加了安全边距，防止发票边缘内容在打印时被裁切。

🛠 Technical Note / 技术说明
This update addresses a known limitation in PDF vector merging where Optional Content Groups (OCG) or transparency masks used in digital invoices were lost. The new version renders each page as a high-fidelity image before placement. 本次更新解决了 PDF 矢量合并中的局限性（即全电发票使用的 OCG 图层或透明度掩模在合并时会失效的问题）。新版本在排版前会将每一页渲染为高保真图像，实现“所见即所得”。
