this change introduces an ssh server to the appview. this server is backed by a charmbracelet/wish app. it is invoked like so: ssh -t appview.host -p 3333 at://.../sh.tangled.pipeline/... the wish app then opens up a TUI for that pipeline job, with live streaming of logs and statuses for all workflows in that pipeline (available a separate tabs). at startup, the appview needs to currently be run with TANGLED_SSH_ENABLED=true, which starts the ssh server on 0.0.0.0:3333 by default.
