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

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

You are done when all of these are true. Check each one yourself:
- Node.js 24 and a Mastra project from create-mastra in ~/my-agents, a git repository
- mastra.service enabled, serving the API and Studio on port 8000, private to the VM's owner, and back after a reboot
- Model calls through exe.dev's LLM integration, with no OpenAI API key on the VM
- Threads, memory, workflow runs, and schedules in ~/my-agents/mastra.db
- The hn-digest workflow, run once and scheduled for 07:00 UTC every day

Run "Set up Mastra by hand" from "On the VM", skipping VM creation and
SSH, then "Add a scheduled workflow". Wait for /health before each
curl to the server. Skip "Give each conversation a VM" unless the owner
asks: only they can create its integration, from their own computer;
never ask for an exe.dev or OpenAI API key instead. Keep port 8000
private: never run share set-public. Finish with https://<vm>.exe.xyz/,
using this VM's name.

Finish with the URLs I should open.
