fix(android): harden edge-to-edge release builds - #2752

Summary

• Remove the Android edge-to-edge opt-out while preserving current inset-safe layouts.
• Route system-bar styling through modern APIs on Android 15+ and keep legacy color compatibility below API 35.
• Add inset-safe CrashActivity handling for system bars and display cutouts.
• Enable release-only R8 optimization and resource shrinking with conservative Cordova, plugin, SSH, and crypto keeps.
• Add one focused unit test covering the opt-out, release shrink configuration, keep coverage, and the narrow SSHTools JMX exception.

R8 note

Maverick Synergy has an optional desktop thread-dump path that references three java.lang.management classes unavailable on Android. The rules name exactly those three classes; there is no wildcard dontwarn, ignorewarnings, dontoptimize, or dontobfuscate rule. Acode does not enable maverick.threadDump.

Validation completed

• npm run test: 33 files, 239 tests passed
• npm run typecheck
• biome ci .
• paid production AAB and APK, signed and minified
• free production AAB and APK with AdMob, signed and minified
• non-empty mapping files embedded in both AABs
• AAB/APK ZIP integrity and signatures verified
• package IDs and launcher/notification fallback resources verified
• DEX output: paid 8,380,120 bytes; free 12,553,664 bytes; local baseline 19,572,936 bytes

Remaining acceptance gates

• Android 14, 15, and 16 manual matrix: gesture and three-button navigation, portrait/landscape, light/dark, keyboard, and cutout profiles
• Manual feature matrix for editor/files, BrowserActivity, fullscreen WebView, crash UI, SAF, terminal notification, network plugins, IAP, and free AdMob flows
• Free AAB Play internal-track upload and clean pre-launch report
• Staged rollout monitoring for startup, plugin loading, crashes, and ANRs

This stays in draft until the remaining device and Play gates pass. The connected Android 16 phone contains Play-signed installs, while local artifacts use the upload key; replacing them would require deleting app data. The local API 36 emulator image is incomplete, so device testing was not forced.
