Settings Slice
This slice owns settings and trust/privacy messaging.
The screen is intentionally simple. This is the right place for local-first copy, future AI-sharing controls, and developer/founder-mode toggles.
LLM connection controls live in presentation/settings_view.dart and persist
through core/llm/llm_config.dart. Provider-specific model discovery and debug
prompt calls are owned by core/llm/llm_service.dart.
