Note

Low Risk
Dependency-only patch version bump with lockfile updates; limited surface area beyond whatever behavior changed upstream in extension-port-stream.

Overview
Updates the extension-port-stream dependency from ^5.0.2 to ^5.0.3, including the corresponding yarn.lock resolution/checksum changes, to address a Chromium behavior change impacting users with large extension state.
