Is your feature request related to a problem? Please describe.
Currently:

• templates without logic or formulas support parse and draft but no other command (e.g., initialize or trigger)
• templates with logic support all commands
• templates without logic but with formulas are handled like contracts with logic

This can be a bit surprising, especially cicero initialize sometimes works when there is no logic (e.g., when a formula is in the template grammar).

Also this means testing logicless templates is somewhat cumbersome / different from other templates.

This can also mean some API calls will throw lower-level exceptions for logicless templates in some cases.

Describe the solution you'd like
More uniform handling of templates with or without logic. For instance:

• Contracts without logic are treated as having empty contract logic (i.e., a contract with a single default initialize clause)
