feat: 适配 Lua 5.1.5 (lua_5.1.5 分支)

- lib/lua 替换为 Lua 5.1.5 官方源码; CMakeLists 删除 5.1 不存在的
  lcorolib.c/lctype.c/lutf8lib.c/lbitlib.c
- 补充 lua.hpp C++ 包装头(5.1 官方不提供, 保持桥接 include 路径不变)
- LUA_OK 兼容宏: 5.1 无此定义(成功返回值为 0)
- luaL_tolstring 兼容: 5.1 无此 API, l_print 改用 lua_tostring +
  lua_typename 兜底(#if LUA_VERSION_NUM >= 502 条件编译, 弹栈逻辑同步分支)
- luaL_setfuncs 兼容: 5.1 无此 API, push_tty_file 改手动循环注册
- I/O 重定向沿用 Registry 方案(自 5.2.4 分支同步), typed interop
  版本自适应断言同步
- 验证: GTest 44/44 通过
