2//! `nativeHost:installShellCommand` - create a `land` (or `code`) symlink in
3//! `/usr/local/bin` pointing at the running executable so the user can launch
4//! the editor from a terminal. Mirrors VS Code's "Install 'code' command in
5//! PATH" command. Uses `pkexec`/`osascript` to acquire elevated privileges
6//! when `/usr/local/bin` is not writable by the current user.
