Subject: [PATCH] fix(query-broadcast-client-experimental): suppress unhandled
 postMessage DataCloneError rejections

Add .catch() handlers to all three BroadcastChannel postMessage calls
to prevent unhandledrejection events when query state contains
non-cloneable values (ReadableStream, Response, File, functions, etc.).

Fixes #10543
