The native layer now emits one JSON object per report, so the service parses
each into a sealed Iperf3Event — start, interval, end, error — and publishes
those instead of opaque lines. Interval samples carry bytes, bits per second,
retransmits and per-stream socket/cwnd/rtt detail; the end event carries sent
and received totals and CPU utilisation. None of that was available while the
output was scraped text.
Anything unrecognised — non-JSON, malformed JSON, an event name a future
iperf3 adds — becomes an Iperf3LogLine rather than being dropped, so
unexpected output still reaches the user.
Failures arrive as an `error` event rather than a non-zero return from
iperf_run_client, so that event is what now marks a run as failed. The
result's rawOutput keeps the JSON lines verbatim, since that is what the
native layer actually produced.
