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

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

You are done when all of these are true. Check each one yourself:
- Marimo, a reactive Python notebook, with SQL support
- The notebook at `https://my-marimo.exe.xyz/`

This VM was not created from marimo's image, so run marimo here
instead: install it with uv, with its SQL extras, and serve `marimo edit`
headless on port 8000 under a systemd service in ~/notebooks, so that
https://<vm>.exe.xyz/ opens it. exe.dev's proxy already requires login.

Finish with the URLs I should open.
