参考所有分组，完成尽量多的内容。禁止顺手扩功能 smoke：锁定build-wasm源码映射前置

结论：build-wasm.sh 现在与 native/source-link 一样先运行六分组 source-map guards，再消费生成配置别名和浏览器 artifacts；同步 build/workstreams source map 与 aggregate 元检查。未新增 CNC 行为，未扩展 smoke fallback。\n\n测试：./check-linuxcnc-workstreams-source-map.sh；./check-linuxcnc-build-source-map.sh；git diff --check；CNC_SIM_ALL_NATIVE_GUARDRAILS_ONLY=1 ./test-all-native.sh；./test-native.sh；./test-linuxcnc-source-link.sh。
