加入自产夹具美术（samples/fixtures，492 KB）

这些文件全部由仓库内脚本生成，无第三方版权问题：
  node scripts/make-fixtures.ts samples/fixtures      # DC6/调色板/文本表/期望网格
  node scripts/make-map-fixtures.ts samples/fixtures  # DT1/DS1/夹具 MPQ

入库后 clone 即可跑夹具相关的校验与页面（verify:all、map.html?data=samples/fixtures），
不必先拿到原版 MPQ。

.gitignore 相应调整：用 `samples/*` 而不是 `samples/`（git 不允许反选被整体排除的目录），
并单独放行 samples/fixtures/*.mpq（那个 MPQ 是我们自己生成的）。原版 MPQ、烘焙图集包
与第三方参考源码仍然不入库。
