v1.3.0 - Experimental German language support

What's changed

German Language Support (Experimental)

• Added experimental support for generating the app with German story text
• Set OATHSWORN_GERMAN=true before running ./setup.sh to download the German version of the app and use its story strings instead of the English ones
• Note: this is experimental and incomplete. Story text, chapter narration text, and choice buttons will be in German, but interface labels (buttons, settings, headers) will remain in English. Audio narration is not affected.
• The German APK is downloaded, SHA256-verified, and cached alongside the English APK so repeated runs skip the re-download

UI

• Popup and event boxes in the story now display a small info icon, making them visually distinct from regular story text
• Audio previous/next track buttons now use the game's own icon assets instead of Unicode characters

Build

• German APK extraction uses resource-only mode (no source decompilation), making the German setup step significantly faster than a full decompile
