/**
 * v0.6 §2.5 — Retrospective stats ETL (회고 입력원 집계).
 *
 * Deterministic aggregation of v0.5 operational data into a markdown
 * report. Called by the `v06-retrospective-stats` routine (weekly cron).
 * Output: `<org>/memory/v0.6-retrospective-stats-<YYYY-MM-DD>.md`.
 *
 * No LLM calls — facts only. Retrospective text body is written by humans
 * who read this report.
 *
 * Coverage of §2 표 회고 작업 inputs:
 *   #1 누락/잉여 stage          — workflows _status.yaml stage status 분포
 *   #2 핸드오프 슬라이스 패턴   — _handoff.md 섹션 분포 (per agent)
 *   #3 Stage별 keep/discard    — goals results.tsv per-stage 비율
 *   #4 author SKILL 패턴       — author-costs.jsonl per-skill, per-step
 *   #5 / #6                    — 빈 섹션 (사람이 회고 후 채움)
