+### Changed

+- `upload_parquet()` now uses the presigned upload session API (`POST /v1/uploads`) instead of reading the entire file into memory before uploading. For multipart mode the file is streamed one `part_size` chunk at a time, eliminating the memory spike that caused OOM on large Parquet files. Falls back to `POST /v1/files` when the server returns 501.
