Detailed Description

LZ4 block-compression handler.

Companion to n_zlib.h that wraps the lz4 reference implementation shipped under external/lz4/. Same self-framing layout as zip_nstr (u32 original size in network byte order + compressed payload), just a different codec inside. Picked when callers want speed over ratio, LZ4 compresses ~25x faster and decompresses ~10x faster than zlib at a ~25 % ratio cost on text / JSON payloads.
