Branch migration

This PR replaces #94 only because its legacy head ref used the retired �gent/ prefix. The source tree and commit history are unchanged: $(System.Collections.Hashtable.oldBranch) and $(System.Collections.Hashtable.newBranch) both point to exact head $(System.Collections.Hashtable.sha) at migration time. Review and merge protection remain required.
