Add Discord APKTool decompilation (Smali source for modding)

- Imported from https://github.com/supermegamestre/Project-Real-Resurrection-3
- APKTool decompilation (Smali bytecode) for modding and rebuilding APK
- Supports both 32-bit (armeabi-v7a) and 64-bit (arm64-v8a) architectures
- Includes full Smali source, resources, and native libraries
- Ready to rebuild APK after modifications with apktool b command
- Added comprehensive README-apktool.md with modding guide

This branch complements the JADX branches:
- Use JADX (main/discord-community) to UNDERSTAND code (readable Java)
- Use APKTool (this branch) to MODIFY and REBUILD APK (editable Smali)

Total: 44,417 files, 538.51 MB Smali source code
