When an upstream request was aborted mid-stream (SDK client timeout,
stream idle watchdog, non-streaming fallback timeout, or user
cancellation), the trace fetch hook waited on a clone of the response
body that could hang forever, so the call never left "pending" in the
trace panel — exactly the silent stall that misled the #766 report.
- captureResponseTraceSnapshot reads the body with abort awareness:
reader.cancel() on abort keeps the partial body, with a 2s grace
backstop for runtimes where cancel cannot wake a hung read.
- The fetch hook now records an error-state call on abort with the
abort reason (e.g. the watchdog's stream idle timeout), duration,
partial response body, and an api_call_aborted event; non-abort
capture failures also record an error instead of inferring ok, and
pre-response fetch rejections carry an aborted flag.
- The trace detail panel shows an "Aborted" badge plus guidance for
aborted calls, and labels the new api_call_aborted phase in all
locales.
