fix(microvm): the relay URL must survive the login profile; deploy.sh must not ship a target symlink

- The first relayed kimi mission (01a0cfc3) bound the node relay, yet the guest
  dialled api.kimi.com through egress with the proxy token: the turn runs in a
  login shell that sources /etc/profile.d/00-image-env.sh (the image's ENV),
  which re-exports the glm/kimi images' baked ANTHROPIC_BASE_URL over ours. The
  turn command now re-exports the base URL after the profile. No key leaked —
  the guest had only the token — but relayed kimi/glm missions could not run.
- deploy.sh excluded `target/`, which matches only a directory; a workstation
  whose target is a symlink copied it to the build host, breaking its builds.
