_compute_rms_windows_wav honours sampwidth for frame arithmetic but
decodes as int16 unconditionally, so an 8- or 24-bit WAV produced
meaningless RMS values and therefore meaningless sections, silently.
The recorder only writes 16-bit, but --dir points at arbitrary
directories. analyze_wav now refuses anything else, turning a silent
wrong answer into a visible one.
_loud_sections closed mid-file sections at last_loud_t + window_dur but
the trailing one at the file duration. A file whose last loud event is
followed by less than min_gap of quiet reported a section stretched by
up to min_gap seconds, and the clip served for it carried that silence.
Now capped at the last loud window, consistent with every other section
and with the score, which only ever covered the loud windows.
DETECTOR_VERSION 2 -> 3 so existing caches are recomputed.
