datap-rs.DataPress 0.4.26

Fast multi-backend (DuckDB / DataFusion) HTTP server over Parquet and Delta datasets.

DataPress turns Parquet and Delta datasets in object storage into fast, typed HTTP APIs — JSON and Arrow IPC — backed by DuckDB or Apache Arrow + DataFusion. The single `datapress` binary bundles both engines and selects one at runtime from `server.backend` in your datasets.toml.
