Process manager templating & game importing (#96)

* feat: add new template options, asahi support, and refactoring

* feat: install dir scanning, validation fixes, progress fixes, download manager refactor

This kind of ballooned out of scope, but I implemented some much
needed fixes for the download manager.

First off, I cleanup the Downloadable trait, there was some
duplication of function.

Second, I refactored the "validate" into the GameDownloadAgent,
which calls a 'validate_chunk_logic' yada, same structure as
downloading.

Third, I fixed the progress and validation issues.

Fourth, I added game scanning

* feat: out of box support for Asahi Linux

* fix: clippy

* fix: don't break database
