- Refactor `AppManifest`: add new fields and rename existing ones - Parse and validate the manifest from an app that is being installed. - Remove deprecated `scoped()` from `Lock` - Create `Tactility/Paths.h` - App loading at boot now properly parses the manifest files of external apps - Properly lock both source and destination locations during app install - Remove LVGL path variants from `AppPaths` and `ServicePaths` - Removed `xPath` base classes for apps and services. There's now `AppPaths` and `ServicePaths`. - Renamed app and service paths: "data" and "system" paths are now "user data" and "assets"
