The output-streaming section described the pipe and reader thread that no
longer exist, including the join-ordering rule that was the reason they were
dangerous. Replaced with how the json_callback path works and why, and an
explicit note not to reintroduce the pipe.
Adds a section on what embedding a CLI in a long-lived app process actually
costs, since that is the recurring trap here: iperf3's main() can leave
process-global state behind because it is about to exit, and this app cannot.
Records what iperf3 does clean up — joined stream threads, closed fds, an
immediately unlinked temp file — with the measurements taken on device, so the
next person does not have to re-derive whether repeated runs leak.

The root README still documented the abandoned approach: iperf3 3.21 binaries
bundled in assets and run through a Process runner, and a lib/ layout that no
longer matched. It now covers the JNI design, the current feature set and how
to test against a local iperf3 server, and says plainly that the binaries
still sitting in assets/iperf3/ are undeclared in pubspec.yaml and therefore
never reach the APK.
docs/README.md gains the threading, pipe-shutdown and stop-handling
constraints that the fixes on this branch depend on, so the next change does
not have to rediscover why the join order and the worker thread matter.
