Registers studio-scoped command groups - app/studio-level surfaces - and (by delegation) the
workbook and sheet groups it contains. Called once at studio module init (see EagerStudio).
Returns void
Remarks
The studio contains a workbook (which contains sheets), so this registers everything. Definitions
belong roughly to the command scope that creates their keys; keeping the three registrars split now
means each set can later move to its own package without untangling one function.
