Erudior Android preview — verified native updater

Optimized ARM64 Android preview with verified native in-app updates.

Source commit: 77fe242

Same-commit two-version Android emulator acceptance passed. Public APK bytes, SHA-256, manifest, signing identity and non-downgrade compatibility were verified. Physical-phone testing remains separate. Install over the previous preview; do not clear app data.

Erudior v0.24.0

Early version: not yet a replacement for homeschool or school.

New: calculator beside quizzes, drills and lessons (basic, scientific or graphing, with history); colored lesson sections and subject colors; sepia, dim and high-contrast themes; formulas in their own panels; in-app updates on Windows, macOS and the AppImage.
