Pull request overview
Adds pacing/“energy” metadata to audio semantic segments to support downstream pacing-aware decisions (e.g., B-roll matching) in the backend audio pipeline.
Changes:
- Introduces a new energy analysis module that computes word rate, pause stats, and classifies segments as low/medium/high energy.
- Enriches Vertex AI semantic + fallback segmentation outputs with
energy_level,word_rate, andpause_count. - Adds two root-level text files that appear to be branch/placeholder markers.

PR description mentions adding an EnergyAnalyzer class, but this module currently only adds standalone functions. Either introduce the class as described, or update the PR description/module docs to match the actual API to avoid confusing downstream users.

create_semantic_segments() (and _fallback_segmentation()) now enrich segments with energy_level, word_rate, and pause_count, but the method docstring still states it returns only text, start, end, and duration. Please update the docstring (and any callers’ expectations, if documented elsewhere) to reflect the expanded segment schema.
