DALP webhook event token.transfer.pending reference

A token transfer was observed before block inclusion and may later finalize or retract.

Delivery contract

Field	Value
Event type	`token.transfer.pending`
Version	`1`
Lifecycle state	`pending`
Counter-signed receipts	No event-specific advice
SDK type	`Webhook.TokenTransferPendingV1`

This row gives advice only. DALP waits for a counter-signed receipt only if the webhook endpoint's counterSignedReceipts value is true when DALP queues the delivery. When the value is false, a normal 2xx response completes the delivery.
