Web Fetch benchmark 1.0.0

Bench 1.0.0 identifies the historical 430-task Web Fetch report's task and scoring contract. The attached benchmark-release.json retains its selected task hashes and scorer identity. The report binding retains dataset, result and archive hashes plus the exact hosted version.

Scorer source: e1b6efc. Browser Eval report build: 8d6684b25bbee324cada008a23dc78b477e46c25.

These metadata attachments were previously public in Browser Eval's report evidence release. The report's access permissions and 2,580 saved results are unchanged. The current 550-task catalog is a separate major edition, bench 2.0.1.

Release identity

This release names the historical 430-task report contract so its results can be reproduced independently of the expanded catalog. The attached selected-task manifest, not installing the package alone, identifies those 430 tasks.

The one benchmark tag identifies both the measurement contract and accompanying tools; no separate tooling tag is required.
