Identical to the windows command, except we don't write to stdio. We're retaining the system we have for logging on macOS, where we push logs over the tunnel and use the OS logger.
I've tested that a build with this command works end-to-end with my new version of Coder Desktop macOS.
Also brings in the soft net isolation changes from `main` of coder/tailscale.
