feat(sds): adds logic to sweep incoming and outgoing buffers

[adklempner]

Problem / Description

Per https://rfc.vac.dev/vac/raw/sds/#periodic-incoming-buffer-sweep :

Periodic Incoming Buffer Sweep
The participant MUST periodically check causal dependencies for each message in the incoming buffer. For each message in the incoming buffer:

the participant MAY attempt to retrieve missing dependencies from the Store node (high-availability cache) or other peers.
if all dependencies of a message are met, the participant MUST proceed to deliver the message.
If a message's causal dependencies have failed to be met after a predetermined amount of time, the participant MAY mark them as irretrievably lost.

Periodic Outgoing Buffer Sweep
The participant MUST rebroadcast unacknowledged outgoing messages after a set period. The participant SHOULD use distinct resend periods for unacknowledged and possibly acknowledged messages, prioritizing unacknowledged messages.
