PR #60467 added a non-snapshot txn->get(table_version_key) in commit_txn,
commit_partition, commit_index and drop_partition to return table_version+1 to
FE as a version-cache hint. A non-snapshot read adds table_version_key to the
transaction's read-conflict range, while update_table_version() bumps the same
key via atomic_add (otherwise conflict-free). As a result, concurrent
commits/imports on the same table now conflict on the version key and fail with
KV_TXN_CONFLICT, causing retries and throughput regression.
Change these reads to snapshot reads. The returned value is only a hint for
FE's version cache (reconciled by CloudTableAndPartitionVersionChecker) and the
real increment is still done by atomic_add, so correctness is preserved while
the read-conflict on the version key is removed.
