On Windows, Zed generated a .ps1 askpass script and set **SSH_ASKPASS**
to 'powershell.exe -ExecutionPolicy Bypass -File ...'. SSH calls exec()
on SSH_ASKPASS which cannot exec a command string, causing:

error: ssh_askpass: exec(powershell.exe ...): No such file or directory

Fix by pointing **SSH_ASKPASS** directly to cli.exe and passing the
socket path via **ZED_ASKPASS_SOCKET** env var, which cli.exe reads
before clap parses arguments.
