Module pipeline 

Cascading codec pipeline: chains type-aware encoding → terminal compressor.

Each ColumnCodec variant maps to a fixed pipeline. The encode_pipeline() and decode_pipeline() functions dispatch to the appropriate chain.

Cascading chains:

• AlpFastLanesLz4: f64 → ALP → FastLanes bit-pack → lz4
• DeltaFastLanesLz4: i64 → Delta → FastLanes bit-pack → lz4
• FastLanesLz4: i64 → FastLanes bit-pack → lz4

The pipeline writes a 1-byte codec ID header so the decoder knows which chain to reverse. This header is read by decode_pipeline().

encode_bytes_pipeline

Encode raw bytes (symbol columns or string data) through a pipeline.

encode_f64_pipeline
