- Added restart_netd_for_hosts_cache() to hosts_enforcer.sh with PID-stamp deduplication to prevent double-restarts across enforcer invocations - Removed explicit netd restart from deploy.sh (caused double-restart that broke ConnectivityService binder link and dropped default route) - deploy.sh: wait 10s after starting focus_daemon.sh for enforcer to complete its single netd restart before companion app install - Misc updates to dns_enforcer.sh and config.sh
