Run daemon at start-up

[da2x]

Is your feature request related to a problem? Please describe.
Increase peer participation and hyperdrive availability.

Describe the solution you'd like
Start the daemon on start-up and let it run indefinitely without starting Beaker.

Pause the daemon in any of these conditions:

• Beaker isn’t running and the device is powered from battery.
• Beaker isn’t running and the device’s is on a metered network connection.

(There are APIs for both of these on Linux, macOS, and Windows.)

Describe alternatives you've considered
The status-quo.

Secondary: Updates
Auto-updates should probably be moved out into this background daemon.

I can take a crack at this if it would be helpful. Basically add a setting that if enabled would launch the PM2 with noPM2DaemonMode set to false, and if disabled, kill the running hyperdrive-daemon and restart it with noPM2DaemonMode set to true? We can display a confirmation window, as this would need to be a "restart beaker to on change" type request.

The pausing on battery and metered service is a neat idea, but I think it would need to be implemented in the hyperdrive-daemon first, as it would need to operate when beaker is closed, and would effect all other clients using the daemon.

@matthewauld +1 for you to hit this but it actually would require a different approach - you need to start beaker, not something else.

It looks like for windows and mac we can use a builtin API (https://www.electronjs.org/docs/api/app#appsetloginitemsettingssettings-macos-windows). For linux we may need to use https://www.npmjs.com/package/auto-launch
