miniflare@4.20260131.0

Minor Changes

• #12186 0c9625a Thanks @penalosa! - Add CF-Worker header to outgoing fetch requests in local development to match production behavior. A new optional zone option allows specifying the zone value for the header. When not specified, the header defaults to ${worker-name}.example.com.

• #12185 f7aa8c7 Thanks @penalosa! - Add timestamp field to the version metadata binding in local development. The version metadata binding now includes id, tag, and timestamp fields, making it easier to test version-aware logic locally.
