- Android toybox ash cannot exec ELF binaries even with -rwx permissions
- runInShell: true wraps in /system/bin/sh -c which refuses ELF
- runInShell: false calls execve() directly, bypassing sh
- Added debugPrint logging to capture actual output in logcat
- The original chmod call used Process.run('chmod', ...) which fails on Android
because chmod is not available in the app sandbox PATH
- /system/bin/sh is always present on Android and can execute chmod on the
extracted binary, setting executable permissions before the first run
- Use const Iperf3Result constructor in tests
- Remove unused import from widget_test.dart
- Fix unnecessary underscore warnings in Consumer builders
- Use initializing formal for iperf3Service field
- Wire up main.dart to call Iperf3BinaryPathProvider.initialize()
