Tinybird Cli Guidelines

This gets you aligned with Tinybird's CLI 4.0 workflow, which simplified everything around a single dev_mode configuration. Instead of juggling flags on every command, you set up your development environment once in tinybird.config.json, then tb build and tb deploy just work against the right targets. It covers the three development patterns (local, branch, cloud), data operations like appending and replacing, and CI/CD setup. The quick reference is actually useful, especially the reminder that it's tb endpoint data, not tb pipe data, and that you should verify commands with help flags instead of guessing. Solid if you're past the basics and want to stop second-guessing which flags to use.
