Changelog

types: WebhookEvent payload fields require narrowing on event.type; un-narrowed access no longer compiles.
the provider response body moved from RevenueError.cause to a non-enumerable RevenueError.responseBody; cause now carries only the underlying JS error. Non-enumerability hides the body from console.error, util.inspect, JSON.stringify and Sentry, while error.responseBody remains a deliberate read. It is not redacted: the content is customer PII, which a secrets list cannot enumerate.
