claude-code owns /etc/claude-code and ~/.claude as declared directories

So the controller's ownership check refuses a second module owning either. ~/.claude is the
operator's at 0700 (it was 0755 on the workstations); of what is inside, the module owns only what it
writes, and the host keeps a directory that is not empty when the module goes (hq ADR 0182).
