Run a query against Cube

This is the one skill that steps outside the CLI. cube api is bound to Cube's console API and cannot reach a deployment's query endpoint, so querying is two CLI calls to get a URL and a token, then a direct request to the deployment.

Preflight

command -v cube >/dev/null || echo "Cube CLI not installed: curl -fsSL https://raw.githubusercontent.com/cube-js/cube/master/install-cli.sh | sh"
cube whoami || echo "Not authenticated. Interactive: cube login. Headless: set CUBE_API_URL + CUBE_API_KEY."
cube context list

jq and curl are also required here, unlike every other skill in this plugin. Check for them and say so if they are missing.
