Pull request overview

This PR advances issue #65 (“Rewrite UI in Compose”) by migrating the Logs screen from XML/DataBinding + RecyclerView to a Compose-based implementation, and introducing a shared Compose scaffold for consistent top app bars.

Changes:

• Replaced LogsDesign’s XML layout + RecyclerView.Adapter with a Compose screen using LazyColumn and a Material3 AlertDialog.
• Introduced MihomoScaffold and refactored SettingsCommonScreen to use it.
• Adjusted Design.composeView to provide a lazy ComposeView, and updated HelpDesign/LogsDesign accordingly.
