for Vue component communication. Document the preference for function props
over $emit for business logic while reserving $emit for DOM-like events.

- Function props for business logic, data operations, and complex interactions
- $emit for DOM-like events, lifecycle events, and simple user interactions
- Implementation patterns with TypeScript examples
- Testing strategies for both approaches
- Migration strategy from $emit to function props

Establishes consistent, maintainable component communication patterns
across the application with focus on type safety and developer experience.
