Utility for creating MongoDB indexes with automatic migration on
IndexOptionsConflict (error code 85).
When an existing index has conflicting options (e.g. TTL value changed), this utility
uses listIndexes() to find the actual index name by key pattern — not a
guessed default name — so it works even when DBAs renamed the index.
