Ettore Di Giacinto 3598dd5890 backend(audio-cpp): keep a nested speaker turn's own label ...

A segment sourced from speaker_turns re-derived its speaker by greatest
overlap. A turn's overlap with its own span is the largest possible, so a turn
nested inside another speaker's turn could only tie with the container, and the
tie went to whichever came first. sortformer_diar binarizes each speaker
independently and sorts by start sample, so the container always comes first
and the interjecting speaker was silently erased from DiarizeSegment.speaker.
choose_segment_spans now carries the label out with the span.

Also pins the nearest-segment fallback against measuring from either endpoint
or from segment position, which a trailing-only stray word could not do, and
exercises the empty-word guard in join_words. Two fixtures that pin a rule but
do not mirror any pinned family are relabelled defensive.
