Investigate ways to turn Ampersand into a "native" app

[NyaomiDEV]

While there's some Capacitor code in the repo, using it has been a mixed bag of data not being persisted and, overall, a community of plugins that are... less than ideal. Also, there's this thing where Capacitor is kind of a framework on its own and it wants to ship Ampersand also as a PWA while I surely want to ship that myself and keep stuff very much separate.

The intention here is to investigate Tauri 2 and try to ship that to mobile; however, I feel like opening this issue section because I don't know if there's other more controlled ways of just having an "enhanced" WebView app that could do justice to our needs.
