fix(nano): correct entry point header inclusion in nano mode

- Add proper header inclusion check in EntryScriptCodegenTest
- Update NanoCapabilityPolicyTest to use correct extension file path
- Fix translator condition logic for nano policy mode entry header
- Add Windows Nano smoke test workflow with proper executable handling
- Include windows_nano_smoke.exe in packaged compiler artifacts
