- lib/lua 替换为 Lua 5.2.4 官方源码; CMakeLists 补 lbitlib.c(5.2 linit 注册 bit32)、删 lutf8lib.c(5.2 无此文件) - I/O 重定向机制改造: 5.2 无 lua_getextraspace → iopath 指针存入 Registry 固定索引(IOPATH_REG_IDX=1), 回调经 get_iopath() 取回, free_lua 时释放 —— 该方案同样适用于更低版本 - typed interop 版本自适应: capture_result() 的 lua_isinteger 分支用 #if LUA_VERSION_NUM >= 503 包裹, 5.2 及以下所有数字统一 CJT_NUM - 测试跨版本适配: PackagePathConfig 接受 require 的两种返回语义; typed 数值断言 EXPECT_INT_OR_NUM 宏兼容有无 integer 子类型; 大整数保真断言仅对 5.3+ 生效(5.2 经 double 必然丢精度) - 验证: GTest 44/44 通过
