- README: Add Option A (direct include) as recommended method
- README: Add Option B (copy) with warning about manual updates
- install.sh: Detect direct include vs copied files
- README: Add troubleshooting for 'Error loading template' after update
The root cause: Moonraker updates the repo, but copied files in
~/printer_data/config/calibration/ don't get updated automatically.
Solution: Use direct include [include open4neptune-new/calibration/*.cfg]
so files are always loaded from the repo.
