Manually fire the discovery pool-replenish tick.

Same code path as the 12:00 UTC scheduler tick — fires each DB- writing discovery rail (Substack + Beehiiv as of 2026-06-01) in parallel with a per-rail 3-min timeout, inserts net-new Publisher rows, and fires a deduped TG digest.

Query params

dry_run: Default true. false actually persists net-new Publishers. Live runs respect the 23h idempotency window unless skip_idempotency=true. skip_threshold: Default false. Set true to force-fire the rails even when the eligible pool is above the threshold (the auto-tick's "pool healthy" short-circuit is bypassed). Use this when you know the pool is about to drain and want to top up early. skip_idempotency: Default false. Set true to bypass the 23h kv-store guard so the operator can re-fire on the same UTC day. pool_threshold: Override AUTO_DISCOVERY_POOL_THRESHOLD env (default 300). per_rail_limit: Override AUTO_DISCOVERY_PER_RAIL_LIMIT env (default 50). Passed as limit to each rail.
