fix: apply Windows subprocess fixes to testing agent and initializer

Browse Source 
Follow-up to PR #89 - apply the same popen_kwargs pattern with
stdin=DEVNULL and CREATE_NO_WINDOW to _spawn_testing_agent() and
_run_initializer() for consistent Windows behavior.

Also fixes typo: _kill_process_tree -> kill_process_tree
