New messaging option send-confirmation = store (default) | propagation. In propagation mode MessageSent fires from the publish path (relay mesh / lightpush relayPeerCount) right after MessagePropagated, with no store polling; finalized tasks no longer re-enter the task cache, so the confirmation is emitted exactly once. Store mode is bit-identical to before. The option flows through both the structured and legacy flat JSON config shapes. Part of the "Store as a startup-only dependency" experiment (step 9).
