Function parseDefinitionInput

parseDefinitionInput(
    def: Record<string, unknown>,
    caller: string,
): {
    description?: string;
    fields?: FieldEntry[];
    groups?: Group[];
    initialStage: string;
    lifecycle?: WorkflowLifecycle;
    name: string;
    predicates?: Record<string, string>;
    roleAliases?: RoleAliases;
    semantics?: Semantic[];
    stages: Stage[];
    start?: StartBlock;
    title: string;
}
Parse one incoming definition at the deploy/diff boundary (caller prefixes the error). Accepts authored content or a fetched definition document — the document envelope and the authoring-only runtime block are stripped (the inverse of the deploy serialisation, so a fetched document round-trips to unchanged instead of fingerprinting its envelope as content, and a hosting kind never changes a definition's version), then the remainder strict-parses against the stored schema: any unknown key anywhere in the tree fails loud.
