Feat: Delete build file after successful installation

### Is your feature request related to a problem? Please describe.

I usually build pretty often so it's annoying when I have my builds lying around when there is a new one available. So it would be great if the old ones were just auto-deleted.

### Describe the solution you'd like

After a successful build installation, just delete that build. This can be a setting in the settings that is toggled `OFF` by default because I'd assume most people would get confused if this was `ON` by default

### Additional context

_No response_

Start by tracing the successful build-installation flow and the existing settings implementation. Confirm where an installed build is retained and how settings are persisted. Done means an opt-in setting deletes the build only after successful installation, while the default remains OFF.
