split-audio-by-words

Purpose

Cutting a long-form podcast clip into per-scene mp3s with raw timestamps always lands on a mid-word boundary sometimes. The klarify scene-07 split clipped at source-49.2s but the word "stakes" started at 49.4s — the per-scene file ended at "...higher" and the rest of "stakes situations" was lost. We didn't notice for two iterations.

This atom solves it the right way: transcribe the source with word-level timestamps, then snap every requested cut point to the nearest word boundary (with operator-tunable preference for snapping before/after the boundary word).
