/**
 * Get build logs for a specific job

 * Usage:
 *   get-build-logs.js <org> <pipeline> <build> <job-label-or-uuid>
 *
 * Examples:
 *   get-build-logs.js gusto payroll-building-blocks 29627 "ste rspec"
 *   get-build-logs.js gusto payroll-building-blocks 29627 019a5f20-2d30-4c67-9edd-87fb92e1f487
 *
 * Features:
 *   - Accepts job label or UUID
 *   - Automatically resolves label to UUID if needed
 *   - Handles step ID vs job UUID confusion
 *   - Outputs formatted logs
