Run any pending knowledge-base migration by querying the deterministic migration chain (`migrate status`) and executing each pending step's documented procedure in-host, with every write delegated to the step's deterministic CLI primitives. Use when the node reader, `doctor`, or `init` reports an out-of-date `schema_version` / legacy flat layout and asks you to migrate, or when the user asks to migrate the knowledge base.
