https://github.com/openai/codex/pull/160 introduced a call to `exec()`
that takes a format string as an argument, but it is not clear that the
expansions within the format string are escaped safely. As written, it
is possible a carefully crafted command (e.g., if `cwd` were `"; && rm
-rf` or something...) could run arbitrary code.
Moving to `spawn()` makes this a bit better, as now at least `spawn()`
itself won't run an arbitrary process, though I suppose `osascript`
itself still could if the value passed to `-e` were abused. I'm not
clear on the escaping rules for AppleScript to ensure that `safePreview`
and `cwd` are injected safely.
