- Create minted-filter.lua to convert fenced code blocks to minted environments for better syntax highlighting.
- Add number-lines.lua to enable line numbering for code blocks in PDF output.
- Introduce symbol-fallback-filter.lua to replace missing special symbols with LaTeX commands.
- Develop table-filter.lua for generating tables with custom styling and borders in LaTeX.
- Create table-wrap.lua to convert pipe tables to longtable format for improved wrapping.

* feat: 优化代码块样式和行号配置，增强可读性和一致性

* feat: 添加代码块和引用块样式优化，提升 PDF 导出视觉效果

* feat: 增强 PDF 导出功能，优化多语言和 emoji 支持

* feat: 更新使用心得，分享系统迁移、散热优化和桌面布局经验

* fix(pdf-exporter): resolve code block page break overlap issue

Add breakable=true to mdframed styles to allow proper page breaks for long code blocks
Move ctexset command after ctex package load
Update template.tex with improved frame handling and spacing
Add documentation in PAGE_BREAK_FIX.md explaining the solution

* Fix template compilation by removing problematic catcode assignments

- Removed catcode modifications from lstinline redefinition that were causing Pandoc template parser errors
- Simplified lstinline to use seqsplit for line breaking without catcode changes
- Template now compiles successfully with LuaLaTeX
- Added comprehensive test file to verify inline code wrapping in tables

* Implement aggressive inline code wrapping for table cells using parbox + seqsplit

- Enhanced both texttt and lstinline commands to use parbox with calculated width
- Added tolerance, emergencystretch, and hbadness settings for better line breaking
- Uses dimexpr to calculate appropriate width accounting for padding
- seqsplit handles breaking at any character when needed
- Comprehensive test files added to verify wrapping in various scenarios
- Should resolve inline code overflow issues in table cells

* 完全修复内联代码在表格中的换行问题

问题根因：
- fix-lstinline.lua filter 会拦截所有 Code 元素，覆盖模板中的定义
- 之前的 texttt 定义使用 parbox 导致内联代码显示为独立行

解决方案：
1. 简化 texttt 为真正内联的版本（无 parbox）
2. 在 table-wrap.lua 中特殊处理表格中的 Code 元素
3. 对表格中的内联代码使用 flexcode 命令（支持换行）
4. 修复 fix-lstinline.lua 中的 LaTeX 特殊字符转义

效果：
- ✅ 正常文本中的内联代码保持内联显示
- ✅ 表格中的内联代码能够正确换行
- ✅ 保持代码背景色和字体样式
- ✅ 支持中英文混合和特殊字符

测试文件：test_inline_debug_table_fixed.pdf, test_specific_wrapping_final.pdf
