### What? Fixes an issue where only the fields from the first batch of documents were used to generate CSV column headers during streaming exports. ### Why? Previously, columns were determined during the first streaming batch. If a field appeared only in later documents, it was omitted from the CSV entirely — leading to incomplete exports when fields were sparsely populated across the dataset. ### How? - Adds a **pre-scan step** before streaming begins to collect all column keys across all pages - Uses this superset of keys to define the final CSV header - Ensures every row is padded to match the full column set This matches the behavior of non-streamed exports and guarantees that the streamed CSV output includes all relevant fields, regardless of when they appear in pagination.
