/**
 * StyleTargetAnalyzer — measures a chapter's quantitative prose metrics and
 * compares them against the project's declared `style-targets.yml` (or the
 * built-in defaults). This is the deterministic counterpart to the qualitative
 * prose STYLE_GUIDE.md files: it turns the guide's numbers ("adverbs 3-5 per
 * 1000 words", "passive < 8%") into measured-vs-target verdicts.
 *
 * Reuses ProseAnalyzer for show/tell and sensory balance; everything else is
 * computed here with the same regex/heuristic style as the rest of the
 * analysis layer. Pure deterministic — no LLM.
