Fix send-on-closed-channel panic in deploy explain mode

It ran: cd /home/evanphx.linux/mn-git/tasker/apps/web && miren deploy -C usv-digitalocean -e NEXT_PUBLIC_API_URL=https://albert-tasker-api.miren.app 2>&1 | tail -20

and later reported:

- Two panic: send on closed channel crashes in the miren deploy CLI for the web build (build succeeded server-side, but CLI exited with a stack trace and left a stuck lock). Cancelling and retrying worked.
  Worth reporting to the miren team if you see it again — looks like a stream callback being invoked after channel close in cli/commands/deploy.go:678.
