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.

The screen could only start a 10s single-stream test and read the result
afterwards. It now renders the transcript as it arrives in a scrolling
monospace view that follows the newest line, exposes the duration and
parallel-stream settings TestConfiguration already carried, can stop a run in
progress, and copies the transcript to the clipboard.
The output field previously built a TextEditingController inside build(), so
every rebuild — one per output line now that output streams — discarded and
replaced it. Replaced with SelectableText, which needs no controller.
Seeds the inputs from TestConfiguration's own defaults rather than a second
hardcoded server address, so there is one default to change.

The root cause of the SIGBUS (alignment fault) crash was casting jmethodID
values to function pointers and invoking them directly. jmethodID is an
opaque JNI type that must only be used via CallVoidMethod/CallObjectMethod
etc. Calling it as a function pointer dereferences garbage memory, causing
SIGBUS at address 0xb1.
Changes:
- Replace function pointer typedefs (output_callback_t etc.) with a struct
storing JNIEnv + callback global ref + jmethodIDs
- All callbacks now go through CallVoidMethod(env, ref, mid, ...)
- Remove getTestProgress() (never used, unused start_time workaround)
- Fix Kotlin arg cast: List<String> -> toTypedArray() (ClassCastException)
- Update UI default server to speedtest.uztelecom.uz
- 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)
- 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()
