/**
 * Single source of truth for the per-call HTTP header merge that both the
 * non-durable `loop/workflows/agentic-execution/llm-execution-step.ts` and the
 * durable `agent/durable/workflows/steps/llm-execution.ts` send to the model.
 *
 * Merge order (later wins):
 *   1. `memoryHeaders` – `x-thread-id` / `x-resource-id`, used by memory-aware
 *      gateways (e.g. Memory Gateway) for server-side enrichment.
 *   2. `modelConfigHeaders` – headers configured on the agent's model config.
 *   3. `callTimeHeaders` – headers passed via `modelSettings.headers` on the
 *      individual stream/generate call.
 *
 * Returns `undefined` when every input is empty, so callers can drop the
 * property from the outgoing request entirely instead of sending `{}`.
