payment.cancelled

A payment was cancelled before capture (abandoned/voided checkout) — distinct from payment.refunded (post-capture reversal). Receivers release any provisional hold/order tied to the payment. S410 registry-integrity reconciliation: caracol + cosmos-pet declared this receiver in apps.json without a matching events.json entry; no ecosystem sender is wired yet (senders:[] until a payment source emits it).
