结论：依据 LinuxCNC emccanon.cc 与 units.h，GET_EXTERNAL_LENGTH_UNITS 返回 user-units-per-mm 而非当前程序单位；新增 G20/G21 后 G92.3 恢复覆盖，native/source-link/test-native 均通过。

(Source basis: LinuxCNC src/emc/rs274ngc/interp_convert.cc convert_length_units rescales G92 axis offsets, and convert_axis_offsets restores #5211-#5219 through USER_TO_PROGRAM_LEN and USER_TO_PROGRAM_ANG on G92.3.)
