- Address further restrictions on actor-isolation by using `nonisolated`
on:
- Combine subjects
- Core Data context/controller
- Blocks
- In previews using inline `@State`, create a custom view instead
- Use `@retroactive` in l10n extensions
- Fix compile error in WireGuardKit
Also, improve filters by constraining related fields:
- Pick countries from the filtered category
- Pick presets from those available in the currently filtered servers
Closes#705
