fix: add timeout to buildx export operation to prevent hanging

Browse Source 
Add a 30-second timeout to the buildxHistory.export() call to prevent
workflow jobs from hanging indefinitely when the buildx dial-stdio
process crashes or becomes unresponsive. The build will continue
with reporting even if the export fails or times out.

Fixes issue where docker run export-build command would hang with
"broken pipe" errors when buildx backend is unavailable.
