1. Various functionalities offered by this tool are now organized into commands (e.g. `felt test`, `felt check-licenses`).
2. The felt tool can now be invoked from anywhere, not necessarily from the web_ui directory.
3. This new structure helps us scale better as we add more commands (e.g. soon a `build/watch` command is coming).
