feat: add --reset and --uninstall options to install script

The install script now provides convenient management options:
- --reset: Stops Pulse, removes config/data, restarts with fresh config
- --uninstall: Completely removes Pulse from the system

Also simplified the post-install message to show these one-liner commands instead of listing manual steps.
