Adds PRV_Cron_Guard hooked on init to re-schedule managed cron hooks when missing after rsync deploys. Delegates to PRV_Cron::schedule() and PRV_Prune_Cron::schedule(). Idempotent. Two wp_next_scheduled() reads per request; no DB writes unless event missing.
Per-call recording of cost and I/O for every LLM probe. New tables prv_call_meta (schema v3) and prv_call_io. New admin pages: Costs (spend drill-down vs $5 cap) and Call Log (paginated + detail drawer). 90-day I/O retention prune via prv_daily_prune cron. P0 security: key never stored; gateway client exposes HTTP status only.
