Fixes #1005 Without linger, user-level systemd services stop when the SSH session ends — even though systemctl --user status shows active (running). Changes to systemd_install(): - Try loginctl enable-linger automatically (succeeds when the process has the required privileges) - If loginctl fails (no privileges), print a clear, copy-pasteable warning with the exact command the user must run New helper: _ensure_linger_enabled() - Fast path: checks /var/lib/systemd/linger/<user> (no subprocess) - Auto-enable: loginctl enable-linger <user> - Fallback: actionable warning with sudo command + restart instructions Tests: 4 new tests in TestEnsureLingerEnabled, 205 passed total
