Defer the strict-mode SLO throw until after run_meta.json and
artifacts_index.json are written so downstream readers (readRunSummary,
portal) see the failure. Record the error in both strict_slo_failure.txt
and the run_meta error field.

Guard all controller.enqueue() calls in the SSE runs stream against the
closed flag and wrap in try/catch to prevent unhandled rejections when
the client disconnects during an async snapshot fetch.
