DurableOutbox class abstract interface

Sender-side at-least-once outbox contract (spec § DurableOutbox).

Every frame is durably appended before it is sent, retained until the peer proves receipt (ackThrough), and replayFrom a reconnect cursor re-sends everything the peer has not yet acked. Combined with the receiver's idempotent ignore of already-applied deltas, this is at-least-once delivery with exactly-once effect.
