houseme c77c5f047a fix(ecstore): defer multipart part.N.meta cleanup until after commit (#4548)
complete_multipart_upload deleted every part.N.meta via
cleanup_multipart_path *before* the authoritative rename_data commit.
If rename_data then failed write quorum, the upload directory was left
with data files but no part metadata, so a retried CompleteMultipartUpload
could never read the parts again and the upload became permanently
uncompletable (client must abort and re-upload all parts).

Move cleanup_multipart_path to run only after rename_data returns Ok,
matching the existing "clean up only after commit" pattern already used
for the old data-dir GC and the upload-dir delete_all. On a failed commit
the staging part.N.meta now survive so the retry can complete.

Add a hermetic regression test that forces rename_data to fail on every
disk (destination bucket dir made read-only) and asserts the staging
part.N.meta are preserved for retry.

Fixes #946.
