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

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

You are done when all of these are true. Check each one yourself:
- `zcode` 3.17.1 on the VM, built from the v3.17.1 tag
- ZCode set to GLM-5.3 through exe.dev's LLM integration, with no Z.ai key on the VM
- A project folder at `~/project` on persistent disk
- A `zcode` tmux session that survives disconnects

Run "Install ZCode by hand", skipping VM creation and SSH. The build
takes several minutes: run long steps in tmux or in the background and
wait for them; don't cut them short. If
`~/.zcode/v2/provider_config.json` already exists, keep a copy as
`provider_config.json.bak` before writing the new one, and tell the
owner. Create the tmux session detached (`tmux new -d -s zcode -c
~/project`) rather than attaching, and reuse it if it exists. Don't start
interactive `zcode` and don't run `zcode --web`. Verify with the
`zcode -p` command in that section, expecting `OK`, and with
`tmux has-session -t zcode`. Finish with the SSH command from "Take a
break", using this VM's name, and tell the owner to run `zcode` inside
the tmux session.

Finish with the URLs I should open.
