/**
 * red-lines-service — main entry. Orchestrates the three tree scanners,
 * the classifier, and the backing detector, then assembles the final
 * RedLineAudit envelope.
 *
 * Pipeline (per openspec/changes/2026-06-11-l2-1-redlines-audit/design.md):
 *   1. Run all 3 scanners in parallel (skills, rules, openspec)
 *   2. Classifier turns MarkdownLine[] into RedLineEntry[]
 *   3. Backing detector re-classifies each entry (cli-backed vs partial vs prose-only)
 *   4. Tally + return RedLineAudit
 *
 * Sub-agent-sid enforcer (Task 2) is also invoked here: it dogfoods Slice 0.5
 * sid-naming-guard and adds any invalid sids as warnings.
