/**
 * kivo cron — Incremental knowledge ingestion for crontab use.
 *
 * Tracks file modification times in kivo_meta table. On each run, only
 * processes files that changed since the last run. Use --full to force
 * a complete re-ingest.
 *
 * Uses BGE embedding + LLM semantic extraction (same as `kivo ingest`).
 * Requires OPENAI_API_KEY or models.providers.penguin-main in openclaw.json.
 *
 * Usage: kivo cron [--json] [--full]
 * Designed for crontab, e.g.:
 *   0,30 * * * * cd /root/.openclaw/workspace && npx kivo cron
