Drift detection and per-mem change synthesis.
reload_if_stale probes each candidate mount’s current_head()
cursor on every operation (no throttle), reloads mems whose
on-disk state has advanced past the engine’s cached head, and
surfaces MemReloaded warnings for handlers that need to
re-derive conclusions from a now-reloaded snapshot. changes_since
produces
the per-entity diff between a stored cursor and the backend’s
current state — folder mounts synthesise from the changelog, the
git-branch hook walks the tree with rename detection, archive
mounts return empty.
