The definitive, foundational skill for ANY Firebase task. Make sure to ALWAYS use this skill whenever the user mentions or interacts with Firebase, even if they do not explicitly ask for it. This skill covers everything from the bare minimum INITIAL setup (Node.js setup, Firebase CLI installation, first-time login) to ongoing operations (core principles, workflows, building, service setup, executing Firebase CLI commands, troubleshooting, refreshing, or updating an existing environment).
