State-independent logic must be moved to module-level functions (avoid god-object controllers)

From conductor/product-guidelines.md §"Code Standards & Architecture":

Modular Controller Pattern: To prevent "God Object" bloat in core controllers (like AppController), all state-independent or utility logic must be moved to module-level functions. Functions requiring class state should accept the instance as an explicit dependency (def logic(controller: AppController, ...)). Massive if/elif dispatch blocks must be refactored into handler maps (dictionaries) of module-level functions.

From conductor/code_styleguides/python.md §15:

15. Modular Controller Pattern

To prevent "God Object" bloat in core controllers (like AppController):

Extract Logic: Move all state-independent or purely utility logic to module-level functions.
Dependency Injection: Module-level functions that require class state should accept the instance as their first argument (e.g., def my_extracted_logic(controller: AppController, ...)).
Handler Maps: Replace massive if/elif blocks (like those in event dispatchers) with dictionaries mapping keys to module-level handler functions.
Inner Class Extraction: Never define nested classes or functions within methods. Move them to the module level.
