Registry object representing a multigroup snapshot.
merkle_root is the hex hash of the Merkle<std::string> root node that maps relation_name → relation_merkle_root for this snapshot. Updates are path-localised: inserting one tuple advances the root through O(log_B) node rewrites, leaving sibling subtrees byte- identical.
Every commit produces a new Multigroup entry under /system/snapshots/<merkle_root> with one child Relation per leaf at /system/snapshots/<merkle_root>/relations/<relation_name>. Snapshots are immutable (disposable=false, exclusive=false); the rest of the system refers to them by hash. A Multigroup is eligible for GC only when its reference_count drops to zero (no BRANCH_TREE still pins it, no pinned cursor still references it).
