pets-setuplisted

Run the installer and report what it wired: ```sh command -v pets >/dev/null 2>&1 && pets install --harness=claude || echo "not-installed" ``` If that printed `not-installed`, the binary is missing. Do not try to install it yourself - print these two options and stop: ```sh brew install TevvvB/tap/termagitchi go install github.com/TevvvB/termagitchi/cmd/pets@latest ``` Otherwise relay the installer's own output. It backs up any config it touches, and `pets uninstall` reverses it. Tell the user to start a new session, because Claude Code reads the status line and hooks at startup.
