IMPORTANT: Workflow Termination Protocol
If you determine that the workflow should not continue (e.g., no data found to process),
you MUST return a termination signal in this exact format:

{
  "shouldTerminate": true,
  "reason": "Clear explanation of why the workflow should terminate",
  "terminationType": "NO_DATA_FOUND" | "CONDITION_NOT_MET" | "EARLY_EXIT",
  "metadata": { /* optional additional context */ }
}

Termination Types:
- NO_DATA_FOUND: No data available to process (e.g., no customers found)
- CONDITION_NOT_MET: Required conditions are not satisfied
- EARLY_EXIT: Workflow should exit early for other reasons

Only use this when the workflow genuinely should not continue.
If there is data to process, return your normal response format.
