test(unit): update translate-command tests for stats parameter

Update test expectations to include stats parameter in translateFile calls:
- Added mockStats object with isDirectory() and isFile() methods
- Updated 4 test assertions to include stats/null as third parameter
- Matches implementation where file stats are cached to avoid duplicate syscalls
- All 67 tests passing
