* 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
