Help me set up xmemory — a memory service you can save to and recall from across sessions.
Use the xmemory CLI for everything below; do not use MCP for this flow.

1. Make sure the CLI is installed: run `xmemcli --version`; if it's missing, install it
   with `uv tool install xmemcli`.
2. Ask me for my email address, then start sign-in with it: `xmemcli auth login
   --email <my address>`. Tell me to check my inbox and approve the sign-in (the email
   shows a matching code so I can tell it's this attempt), and wait until
   `xmemcli auth status` says I'm authenticated. If email sign-in isn't supported by
   your xmemcli version, fall back to `xmemcli auth login`, which opens the console in
   a browser.
3. Check whether the `xmemory-instance-creation` skill is available in your
   environment. If it is, use it now. If not, install it — run
   `npx skills add xmemory-ai/xmemory-skill --agent '*' -y` — and then use it; if the
   install isn't possible here, tell me and I'll paste the skill text.
4. The skill covers the rest: a short interview (one question per message, my choices,
   nothing created without my go-ahead), creating the instance with xmemcli, and the
   instance-specific setup printed by the CLI.
