Set up Pi on this VM by following the exe.dev recipe at https://exe.dev/deploy/pi.md from top to bottom.

The recipe's example VM name is my-pi. This VM's name is the output of `hostname`: use it wherever the recipe writes my-pi. Skip the step that creates the VM; you are on it.

You are done when all of these are true. Check each one yourself:
- Pi answering through exe.dev's LLM integration, with no API key or sign-in
- A Git repository at `~/project` on persistent disk
- A `pi` tmux session that survives disconnects

Use the preinstalled Pi; do not install another copy. If `pi --version`
is older than 1.4.0, run `exeuntu update pi` (without sudo). Run the
VM-side setup in "Start coding". Create tmux detached
(`tmux new -d -s pi -c ~/project`) rather than attaching. Reuse the
session if it already exists, and don't add the tmux setting twice. Do
not launch interactive Pi; leave its first-run question to the owner. Do
not change `~/.pi/agent/auth.json`, `settings.json` or the `exe-dev`
extension. Verify from ~/project with
`pi -p --model gpt-6-luna@llm "Reply with exactly: OK" </dev/null` and
check `tmux has-session -t pi`. Skip the later optional instructions and
FAQ. Finish with the SSH command from "Take a break", using this VM's
name, and tell the owner to run `pi` inside it and choose "Use exe.dev
LLM integration" when Pi asks.

Finish with the URLs I should open.
