/**
 * Cross-machine presence (ADR 0016), phase 1: the git-refs transport.
 *
 * publishPresence(): serialize this machine's live sessions into a presence
 * blob and force-push it to `refs/harnery/presence/<machine>` on origin —
 * change-batched (only when the blob materially changed) with a keepalive
 * (~5 min) so peers can distinguish "no change" from "machine gone".
 *
 * fetchPresence(): throttled fetch of every peer machine's presence ref.
 *
 * readRemoteMachines(): parse the locally-known refs into render-ready rows
 * (self machine excluded, stale blobs dropped).
 *
 * All entry points are fail-silent and gated on `presenceEnabled()` — presence
 * must never break a hook, a render, or a repo with no origin.
