Subject: Bugfix: fix process leak in PythonWrapper::InvokeCommandWithArgs

It now waits up to 10 seconds for a graceful exit and falls back on
the equivalent of a SIGKILL. The caller is assumed to have signaled to the
process through `in_cb` that an exit is desired.

Also:

* Fix graceful exit path of transcribe_v2.py.
* Add toggle to enable/disable preview text. It is enabled by default.
* Constrain transcription temperature to 0.0. This keeps latency more
  predictable at the cost of some accuracy.
