 * Task 2 plan 2026-05-29-supplier-webhook-fast-fail-and-stuck-cleanup.md
 *
 * Tests the fast-fail guard in RouteSupplierLeadJob::handle():
 * if supplier_lead.error contains a terminal pattern ('does not support',
 * 'platform mismatch', 'no matching supplier_project') and processed_at IS NULL,
 * the job marks processed and exits without writing to failed_webhook_jobs.
 *
 * Correction 1/2: uses RouteSupplierLeadJob (not ProcessSupplierWebhookJob).
 * Correction 3: fast-fail inserted between the 2 existing idempotency guards
 * and parseProjectField call.
