满庭芳·源流归一

结论：LinuxCNC rs274ngc 源码移植边界继续收拢。已将 rs274ngc 头文件纳入 manifest 跟踪，core 编译组仍只包含可编译源文件；启用 CNC_SIM_ENABLE_LINUXCNC_RS274_BACKEND 时 API 默认使用 LinuxCNC rs274 后端；M428/M429/M430 与 5axis/TRT/TDR/RTCP 相关路径继续保持来自 LinuxCNC 源码或 remap 配置的薄桥接。

验证：./test-linuxcnc-source-syntax.sh；./test-linuxcnc-api-native.sh；./test-native.sh；./test-linuxcnc-source-link.sh。
