close.onOpportunityWon run when an opportunity enters a won status.
automations/on-close-opportunity-won.automation.ts
account selects a named Close binding; the project binding is the default. Automate.ax creates and maintains the Close webhook and verifies each delivery with Close’s signing secret.
Returns a CloseEvent whose data is the won CloseOpportunity. Close emits an opportunity update; Automate.ax classifies it by data.statusType === "won". All semantic events preserve the shared Close event envelope.
