/**
 * v0.6 — JSONL → SQLite (FTS5) rotation cron.
 *
 * Per docs/plan/v0.6-default-workflow-tuning.md §4.3 + §4.6 + §4.7.
 * Runs nightly (00:00) via `archive-rotate` cron. The hot tier
 * (`<org>/memory/*.jsonl`) keeps the last 7 days; everything older is
 * moved into `archive.sqlite` and *deleted from the JSONL* to keep grep
 * cheap.
 *
 * Inputs scanned:
 *   - `<org>/memory/*.jsonl`           (signals.jsonl, decisions.jsonl, …)
 *   - `<org>/memory/route-events.jsonl` (v0.5/v0.6 route + author + spawn)
 *   - `<org>/memory/cron-logs/*.jsonl` (any future jsonl logs there)
 *
 * Each archived row gets a normalized `event_type`. Lines that already carry
 * a recognized `event_type` field keep it; otherwise default to
 * `routine_log` (backward-compatible with v0.5 jsonl files).
