chore(release): bump to 0.1.17

v0.1.15 update proved the pipeline end-to-end (download, verify, swap OK)
but the app never reopened: the handoff runs in a systemd transient unit
whose default KillMode=control-group sweeps the process tree when the
script exits, killing the backgrounded relaunch before Electron started.
Two fixes: start the unit with KillMode=process, and setsid the relaunch
(nohup fallback) so it detaches from the unit session entirely.
