/**
 * Regression guard for the single deliberate Sentry capture path.
 *
 * Before the overhaul a failed tool job was captured twice (processToolJob
 * catch + worker.on("failed")) and wrapped in new Error(String(err)), which
 * produced frameless events. These tests pin the contract: one reportError
 * call yields exactly one captureException with the ORIGINAL error object,
 * and the throttle allows one capture per distinct signature.
