Kami V1.9.3

Changelog code renders monospace again, plus sturdier checks.

Changelog

1. Monospace changelog code: CN and KO changelog templates now define the --mono stack, so inline <code> (versions, commands) renders monospace instead of falling back to serif, matching the English changelog.
2. Sturdier PDF checks: the orphan, density, and resume-balance checks report a clean error on a malformed or empty PDF instead of crashing with a traceback.
3. Resilient highlighting: syntax-highlight colors load lazily, so importing the build tools no longer reads design tokens on a half-installed checkout.
4. Tighter tests and docs: density, rhythm, and orphan logic gained pure test seams; the README template count and sitemap dates were realigned.

更新日志

1. 等宽的更新日志代码：中文和韩文 changelog 模板补上 --mono 字体栈，内联 <code>（版本号、命令）恢复等宽显示，不再退化成衬线体，与英文版一致。
2. 更稳的 PDF 检查：孤行、密度、简历平衡检查遇到损坏或空 PDF 时输出干净的错误，不再抛 traceback 崩溃。
3. 更健壮的高亮：语法高亮配色改为惰性加载，导入构建工具时不再在半安装环境下读取设计令牌。
4. 更严的测试与文档：密度、韵律、孤行逻辑新增纯函数测试种子，README 模板数量与 sitemap 日期同步修正。
