feat: Add split APK support

[Aunali321]

Summary

Add --splits CLI option for patching split APK bundles.

• --splits accepts Map<String, File> (e.g. --splits arm64_v8a=split_config.arm64_v8a.apk)
• File existence validated at parse time
• Constructs Apk.Split when splits provided, Apk.Single otherwise
• Patched splits copied to <output>/splits/, resources applied, signed
• Split files passed through to ADB/root/local installers
• Added to both PatchCommand and InstallCommand

Test plan

• compileKotlin passes
• End-to-end: full APK — 60/60 patches pass
• End-to-end: split APK bundle (35 splits) — 60/60 patches pass
• Device install via adb install-multiple — success
• App launches and runs without crashes
