docs(migration): add make-install-to-package runbook and no-move continuity tests for #50
Migration runbook at docs/install/migrate-from-makeinstall.md covers the mandatory remove-then-install path, why over-install is forbidden, no-move continuity guarantees, and reset-to-dormant expectations. Acceptance criteria MG-1 through MG-4 added to the install criteria section. Containerized tests verify no-move continuity: existing group makes sysusers a no-op, existing store dir makes tmpfiles a no-op, hand-edited config survives as a non-database file, and store schema is caught up by the upgrade-path migration. Dead code from a prior merge removed. Co-authored-by: CommandCodeBot <noreply@commandcode.ai>
