looks like the async nature of the
onMessageExternalis still brittle/evolving according to codex, the pattern we previously had no longer works because of new changes in chromiums messaging flow. Check out the responses section here: https://developer.chrome.com/docs/extensions/develop/concepts/messagingThis hardens the external runtime bridge used to retrieve stored RPC payloads for large transaction flows. It changes the external message handler to use sendResponse with an explicit async channel return, improving compatibility with runtime messaging behavior. It also broadens sender origin detection to support sender contexts that expose origin rather than URL, while keeping existing origin checks intact. Together this prevents valid payload fetch requests from being rejected or dropped in each send transaction and wallet send calls flows.
