Research direction

Start by reproducing the import from /home/rasberry/testcam.py using Picamera2 and Preview on the reported Raspberry Pi 4 and Raspberry Pi OS setup. Read picamera2/init.py and the libcamera import path, then trace the missing CnnEnableInputTensor symbol in _libcamera.cpython-313-aarch64-linux-gnu.so. Done means the Picamera2 import completes without the undefined-symbol error.
