feat(extension): Add DroidKlipp extension (#804)

* Add DroidKlipp extension

* fix(extensions): restart adb_monitor and redeploy monitor on DroidKlipp update

The update flow only ran git_pull_wrapper, which left the running
adb_monitor service executing stale in-memory code. It also never
rebuilt the deployed ~/droidklipp_monitor.py, since that file is
generated by the installer rather than tracked in the repo.

- stop adb_monitor before the pull, start it after (mirrors mobileraker)
- after pulling, re-deploy droidklipp_monitor.py into $HOME so the
  service picks up the updated code
- best-effort restart the service if the update fails

* fix(droidklipp): clean up comments and update website link in metadata
