Stopping a test shuts down the control socket, so iperf_run_client() returns
-1 with "unable to send control message ... Broken pipe". That is the
expected consequence of the stop, not a fault, but the bridge read the
negative return as a failure — so pressing STOP left the UI showing
"Error (exit 1)" above a broken-pipe message.
The bridge now consults its own g_stop flag before classifying the outcome,
and the distinction travels up as Iperf3Result.stopped so the status line can
say "Stopped". A stop is reported with exit code 0: the run ended the way the
user asked it to.

_isRunning was never cleared on the timeout path, so a single timed-out run
locked the app out of starting another until it was restarted. It is now
cleared in a finally block covering all three exits.
Output was buffered inside the service and only handed over once the run
finished, so the UI showed nothing until the end despite the native layer
streaming line by line. The service republishes each line on outputLines and
the view model appends to a transcript as they arrive.
The channel handler was re-registered on every run and dereferenced
_runCompleter with `!`, which threw once a late callback arrived after the
field had been nulled. It is registered once in the constructor and reads the
completer through a local.
Also drops the duplicated argument list in favour of
TestConfiguration.toCliArgs(), so the flags the UI sends have one definition.

- Switch from bundled iperf3 binary (Process.start) to JNI compilation
- iperf3 3.21 source API was incompatible (start_time, iperf_strerror, etc.)
- iperf3 3.19 source is proven to work (used by CellularLab)
- CMakeLists.txt updated: config.h generated into cpp/iperf/ for correct include paths
- iperf_jni.c fixed for 3.19 API (no start_time on iperf_test)
- getTestProgress() returns g_test->duration as fallback (no real-time elapsed tracking yet)
- NDK CMake pinned to 3.22.1
- UI layer updated: removed Iperf3BinaryPathProvider references
- Tests updated: TestRunViewModelTest matches new service interface
- pubspec.yaml: removed iperf3 assets bundle, added http dependency
- AndroidManifest: INTERNET permission (needed for hostname resolution)
- 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()
