Create editOperations.ts with EditOperation type union covering all 5 operation types (addNode, removeNode, updateNode, addEdge, removeEdge). Implement applyEditOperations function with batched immutable updates, proper ID generation, and validation with skip tracking. Add narrateOperations function for human-readable summaries.
Create contextBuilder.ts with WorkflowContext interface and buildWorkflowContext function that strips base64 data, history arrays, and internal state. Add formatContextForPrompt function for system prompt injection.
Both modules are pure TypeScript with no UI or API dependencies.
