macOS runner exit node support

[seokgyo]

Hi,

I’m trying to use the tailscale/github-action in a GitHub Actions workflow running on a macOS runner (macos-15) with an exit node.

While the same workflow works fine on Linux runners, it doesn’t seem to work properly on macOS.

My questions are:

• Is exit node mode currently supported when using this action on macOS runners?
• If it is supported, are there any known limitations or required flags to make it work?
