按规划持续工作

结论：浏览器 interpreter smoke 和 INI panel UI 已接入 vendored LinuxCNC 五轴 switchkins remap 执行路径，只复制 LinuxCNC sample machine 文件到 WASM FS 并调用 SDK C ABI；host 聚合 smoke 通过，未新增 JavaScript M428/M429/M430 或运动学语义。

 `loadToolTable()` accepts `{ randomToolChanger: true }` to select the
 LinuxCNC random-toolchanger branch before calling vendored
 `tooldata_load()`. The SDK only forwards that runtime boundary flag.

+`runFiveAxisRemapFile()` is a narrow host boundary for vendored LinuxCNC
