Pull request overview
该 PR 修复 preview-ref 悬浮预览气泡中，图片/表格编号总是显示为 1、与正文实际编号不一致的问题；通过在生成预览内容时复用原文档已计算好的 label binding 来保证编号一致。
Changes:
- 在生成预览内容时将 label id 传入预览生成逻辑，并尝试对 figure/table 的编号宏进行局部覆盖以读取原文档 binding。
- 新增开发记录文档
devel/0800.md，描述问题背景、原因与测试步骤。

[0800] 图片/表格 preview-ref 的编号不正确
如何测试
2026/5/11
What
preview-ref 预览气泡中图片/表格的编号总是显示 1，与文档中的实际编号不一致。
Why
preview-ref 会把引用目标片段取出来，在 tooltip 的临时文档中单独排版。
图片/表格宏在展开时会调用
next-figure/next-table，而临时文档中的figure-nr/table-nr从 0 开始，所以预览里的编号总是变成 1。How
label-preview。small/big-figure或small/big-table时，局部覆盖the-figure/the-table为(get-binding id)。这样保留原有图片/表格宏的渲染流程，只让 tooltip 中显示编号读取原文档已计算好的真实 binding。
