Interface guidance

• This package defines small contracts shared by lower layers. Keep it cheap to import and independent of UI, controllers, services, repositories, and concrete backends.
• Contracts state observable lifecycle, ownership, mutation, and failure semantics; implementations may strengthen but not weaken them.
• CoreRuntime is mechanism-neutral. Preserve semantic exit codes, startError(), callback order, serialization, and bounded stop expectations; use process terminology only for actual OS processes.
• Storage contracts intentionally expose live mutable collections. Editor bindings translate widget/configuration values but do not own runtime policy.
• Shared encoders support CoreConfiguration and compatible mappings; serialization failures retain useful context.
• Verify import independence and representative implementations for lifecycle/error, serialization, and live-storage semantics.
