Set up Antigravity CLI on this VM by following the exe.dev recipe at https://exe.dev/deploy/antigravity-cli.md from top to bottom.

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

You are done when all of these are true. Check each one yourself:
- Antigravity CLI (`agy`) in `~/.local/bin`, on the PATH, printing its version
- A Git repository at `~/project` on persistent disk
- A detached `agy` tmux session in `~/project` for work at the keyboard later

Run the VM-side commands in "Install Antigravity CLI" only; skip creating
the VM. Do not start `agy` itself, and do not run `agy remote-control start`:
signing in to Google is the owner's step (a link and a code they paste),
and the daemon refuses to start until they have. Do not set
`modelProvider` or a Gemini API key. Create the tmux session detached
(`tmux new -d -s agy -c ~/project`) rather than attaching, and reuse it if
it exists. Verify with `~/.local/bin/agy --version`, `git -C ~/project
status` and `tmux has-session -t agy`. Skip the later sections and the
FAQ. Finish by telling the owner to run `ssh my-antigravity.exe.xyz` with
this VM's name and follow "Sign in with Google" and "Keep it on with
Remote Control".

Finish with the URLs I should open.
