fix: Android 15+ network, anti-detect bypass, Windows AIDL build

1. Network permission fix (Android 15/16):
   - Add NetworkPermissionCompat to disable framework permission cache
   - Hook checkPermission/checkPermissionForDevice in IActivityManagerProxy
   - Grant INTERNET and related network permissions for virtual apps
   - Fixes WebView blockedNetworkLoads on Android 15+

2. Anti-virtual-detection bypass:
   - Skip known anti-detect ContentProviders in BActivityThread.installProviders()
   - Covers Meituan HadesContentProvider (com.ztuni), Douyin SecurityGuard, etc.
   - App continues running instead of calling System.exit()

3. Windows AIDL build fix:
   - Strip AIDL-generated 'Using:' comment lines that contain backslash paths
   - Prevents Java compiler 'illegal Unicode escape' error on Windows

Refs: fixes #44 (partial)
