Suppress console-window flash on subprocess spawn (CREATE_NO_WINDOW); bump 0.1.2

paths::quiet_command sets CREATE_NO_WINDOW (0x08000000) on Windows so
short-lived child processes (wsl.exe -l -q, where claude, wsl.exe -d X
bash -lc 'command -v claude') don't briefly allocate a real console
window and flash on click. Used by both paths.rs and cli_usage.rs.
