### What problem does this PR solve?
Issue Number: None
Related PR: None
Problem Summary:
Failed or cancelled OUTFILE queries could leave already rolled files,
partially published files, or unfinished object-storage multipart uploads.
Parallel result receivers could also finish independently before another
receiver reported a failure.
This change tracks exact file ownership in each OUTFILE writer, keeps
cleanup callbacks until the FE confirms that every result receiver reached EOS,
and broadcasts commit or rollback to all participating BEs. It also adds an
explicit writer abort path for multipart uploads and cleans up an incomplete
success marker without hiding the original query error.
