所有模板目录改为中文名，并入幻灯片与科技报告两个仓库（#3）

目录改名（git mv 保留历史，包名不变）：
  exam/   -> 试卷/
  form/   -> 年度考核登记表/
  form2/  -> 劳务发放说明表/
  course/ -> 课程执行大纲/

改名即可编译：实测 6 个模板在含中文的目录下 XeLaTeX 均零报错，
PDF 逐页文本与改名前的版本完全一致（0 页差异，仅元数据时间戳变化）。

并入两个此前独立维护的仓库：
  ouc-slide-latex-template  -> 幻灯片/
  ouc-report-latex-template -> 科技报告/
带入了 theme/ fonts/ logos/ figs/ cls/ input/ 与 fontawesome.pdf，
字体随模板附带（无须在系统安装）。中间文件一律不入库。

同步修正的文档：根 README 目录表改为中文名并说明统一维护；
四个子 README 的标题；ouclw.sty 注释里对 form/ 的交叉引用；
幻灯片与科技报告 README 里「从旧仓库 clone」「按年份切分支」等已失效的说明
（并入后只有 main 一个分支，各年份 TeX Live 通用）。

两个迁入模板的 PDF 保留源仓库原版（逐字节一致），未重新编译：
源 PDF 出自 TeX Live 2026，本机为 2022，重新编译会让结尾页装饰层定位
产生细微偏移，保留原版以保证样张与原来完全一致。
