新增 includes/dbgstack.vp: 挂起主线程取 x64 CONTEXT + RBP 链逐步取证 + 栈扫描兜底(4KiB 分块 ReadProcessMemory)；按 <exe>.stackmap 下界查表输出 <文件>.vp:行 (函数)；控制台 ASCII 输出并双写 UTF-8 <exe>.stackdump.txt；ASan 与 DbgHelp 冲突显式降级不静默；lock cmpxchg 原子重入（不用 InterlockedCompareExchange: x64 上是编译器内部函数、无导出符号）。 新增/补 w32 头: win32dbghelp.vp(新)、SetConsoleCtrlHandler、x64 CONTEXT、ReadProcessMemory。 parser.vp/tokens.vp: [N]T/[]T/const [N]T 脱糖为 t.CArray；新增 union NAME: 语句(Keyword.Union 追加表尾)；list[rawptr[AST]] elem_size 2/4 改 8；新增 _record_parse_err_ctx 把 token 类型与前后 token 并入错误消息，去掉 [AST] SyntaxError 遗留单行 printf。 asm.vp: 整文件迁移到 __asm__/asminp/asmout/裸 ASM_DESCR。
