fix: handle quoted arguments in shell-exec on macOS

Use shlex::split to properly parse shell-style quoted arguments
when spawning commands on macOS. Previously, args were split on
whitespace without respecting quotes, causing commands like
`shell-exec open -a "Microsoft Outlook"` to fail because the
quoted app name was split into separate arguments.

Fixes #1337
