Purpose
Allow
deletion-vectors.merge-on-readto be configured globally without rejecting non-DV tables.The option remains a pure configuration value, but is ignored by validation and read behavior when deletion vectors are disabled. Existing deletion-vector safety checks and merge-on-read restrictions for DV tables remain unchanged.
