install_nano_service printed "enabled and started" straight after systemctl restart, which returns as soon as the process is forked. An upgrade that keeps an old felis.toml the new binary rejects (an [[auth_source]] without a prefix, say) left the unit crash-looping in auto-restart while the installer reported success, and every login through the proxy failed. The install now waits two seconds and asks systemctl is-active. A unit that exited is in "activating (auto-restart)", which is-active does not count as active; on real systemd a unit whose process exits 1 under Restart=on-failure reads activating/auto-restart and is-active returns non-zero, while a running one reads active/running and returns 0. On failure the install prints the unit's last 20 journal lines and stops. This also surfaces a nano unit locked out of an existing 0700 /etc/felis. The harness runs the extracted function with systemctl stubbed both ways. Without the check, the dead-unit cases fail.
