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

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

You are done when all of these are true. Check each one yourself:
- Cal.diy from the official Docker image, with a PostgreSQL container, started with Docker Compose
- Its runtime variables and generated secrets in an `.env` file
- Cal.diy at `https://my-cal-diy.exe.xyz:3000/`, ready for the setup wizard

Finish with the URLs I should open.
