Test 2 skeleton: openwakeword loads via --no-deps split, scores print

 **Audio note:** The Pi's USB Speaker Phone only supports 48 kHz natively. We set `PA_ALSA_PLUGHW=1` at the top of every test's `main.py` (before importing sounddevice) so PortAudio opens via ALSA's `plughw:` device, which auto-resamples to the requested 16 kHz.
 
+**openwakeword install note:** openwakeword 0.6.0 declares a hard `tflite-runtime` dep that has no Python 3.13 wheel; we install openwakeword with `--no-deps` from a separate `requirements-nodeps.txt` and pin its real runtime deps in the regular `requirements.txt`. `bin/deploy` auto-installs `requirements-nodeps.txt` after `requirements.txt` if it exists.
