TermiNexus 3c6fb1d246 chore(test): 初始化回归测试仓(新增 .gitignore,TestsOverview.md 改为 README.md)
把 Test/ 纳入 https://git.gvsds.com/GVSDS/Viper_RegressionTesting 。

1) 新增 .gitignore —— 只保留测试源码,剔除全部构建产物:
   目录   **/output*/(output / output_opt / output_orig / output_verify / output_dbg)、
          **/temp*/(temp / temp_opt)、**/.tpv_build/
   二进制 *.exe *.obj *.o *.out *.a *.lib *.dll
   中间物 *.ll *.vpi *.pyi *.deps.txt *.deps.json *.doc.json *_sha1_map.txt
          _pyi_cache_v1.pkl _pyi_cache_v1.sig.json _shared_sym.json _phase1_manifest.json
   其它   build_all.txt(构建日志)、*.log、__pycache__/、*.bak、IDE 目录
   保留   App/*.vp、project.json / project_opt.json / project.vpj、README.md、两个 .py
   实测 `git add -A --dry-run`:196 个文件,无任何构建产物混入。

2) TestsOverview.md → README.md(作为仓库首页文档)。

3) SequentialRegressionTest.py:7 处 TestsOverview.md 引用同步改为 README.md
   (文档串、OVERVIEW 路径、read_test_order 文档与报错文案、argparse description、
   启动横幅);同时修正入口路径 PROJECTRANS —— 旧值 <root>/Projectrans.py 已不存在,
   改为 <root>/TransPyC/Projectrans.py(与 regression_test.py:45-48 记录一致),
   否则本脚本会以 "can't open file" 全量失败。
   regression_test.py 无需改动:它按目录扫描 project.json 找项目,不引用该文档。
