Detailed Description
A named mutable reference to a branch-tree root.
target_hash is the merkle_root of a BRANCH_TREE — a Merkle<std::string> root mapping mg_name -> mg_hash. Path resolution walks the branch tree to translate /system/branches/<n>/multigroups/<mg>/relations/<rel> into the right /system/snapshots/<mg_hash>/relations/<rel>. Empty string means the branch has no commits yet (unborn).
Branches are the sole mutable pointer in the system; concurrent writers serialize through LifecycleManager::Contention because the BRANCH object_type carries exclusive=true. Readers never contend — they resolve the branch through its tree to the immutable Multigroups and operate on those.
