v1.3.4

Add choice of installers 🔧

Summary

Adds a third installer option alongside Stock and Shizuku - a Legacy installer mode. This lets users delegate APK installations to an external installer app (e.g. InstallerX, App Manager) via a custom ContentProvider, bypassing Android's "Install Unknown Apps" restriction for the source app.

What's included

• Installer mode selector in Settings - segmented button to switch between Stock, Shizuku, and Legacy
• Installer app chooser - bottom sheet picker showing all compatible installer apps with their icons
• Settings migration - existing users with Shizuku enabled won't lose their preference on upgrade

Why this matters 🛡️

Users with Android's Advanced Protection enabled cannot grant "Install Unknown Apps" permission to any app. This feature provides a clean workaround by routing installations through a privileged installer that already has root/Shizuku access, without requiring any new app permissions.
