voice_mode WSL playback probe, subagent_worktree._run_git, cua_backend loginctl/xprop probes lost their explicit stdin= (and one line-wrapped past the encoding= same-line rule); lazy_deps._run carries it via _SUBPROCESS_KW so mark it for the guard. Fixes tests/tools/test_subprocess_stdin_guard.py and tests/scripts/test_footgun_subprocess_encoding.py (green on base).
