/**
 * Delete a webhook endpoint (`DELETE /v1/webhook-endpoints/{id}`); deliveries stop immediately.
 * Cannot be undone (create a new endpoint to resume; it gets a new signing secret).
 * WRITE: previews unless `confirm: true`; the preview shows the endpoint that would be deleted.
 *
 * @param input.account - Account name (secret `granola-<account>`). Required. @param input.secretName - Secret override.
 * @param input.webhookId - `whe_…` id. Required.
 * @param input.dryRun - Preview only. @param input.confirm - `true` to delete.
 * @returns Preview `{ dryRun: true, current, request }`, or `{ executed: true, result: { id, deleted: true } }`
 *
 * @example
 * import deleteWebhook from 'kody:@charlesmatte/granola/webhooks/delete'
 *
 * const preview = await deleteWebhook({ account: 'work', webhookId: 'whe_2mKr8fQxLp7Ta3' })
