feat: keep auto-start but via nohup & to avoid hermes kill, remove ntfy, passive dashboard

- __init__.py: re-add auto-start but via nohup (bash -c "nohup {bin} --quiet > /tmp/sshx_link.txt 2>&1 < /dev/null & echo $!"), pid to /tmp/sshx.pid, link to /tmp/sshx_link.txt, _is_alive checks pid file, _run_sshx uses nohup, _stop kills pid file
- dashboard/plugin_api.py: same nohup auto-start thread (3s delay), _is_alive checks pid file, /status reads link file, /start uses nohup, no ntfy
- dashboard keeps passive UI (only show current link, poll every 3s) - hermes no longer kills background shell
- bump v2.3.0
