Offline-first store-and-forward buffering for pamoja: durable queues behind the core Store trait.

Offline-first store-and-forward buffering for pamoja.

Devices on intermittent links append records while offline and drain them in order when a link returns, so a node that is disconnected for hours or days loses nothing. This crate provides durable first-in first-out implementations of the core Store trait:

• [MemoryStore] - a fast in-memory queue, optionally capacity-bounded so a full queue becomes an explicit backpressure signal.
• [FileStore] - a crash-safe on-disk queue that survives power loss, for the power-loss-safe field logging the mission depends on.

Both buffer raw bytes, so an application pairs a Store with a Codec to persist encoded payloads and a Transport to forward them when a link appears. [drain_to] is the forward half: it publishes buffered records onto a transport in order, removing each only after it is sent, so a failed link loses nothing.
