/**
 * Web-standard `TransformStream` wrappers for every codec, so ZipKit drops into
 * any `pipeThrough()` pipeline (`fetch` bodies, files, sockets).
 *
 * gzip / zlib / raw-deflate are backed by the platform's native
 * `CompressionStream` / `DecompressionStream` when present (Node 18+, Bun, and
 * modern browsers) — true incremental streaming with no buffering. The other
 * codecs (zstd, lz4, snappy, brotli, lzma, bzip2) are one-shot in the engine,
 * so their streams buffer the input and compress on flush; this still composes
 * cleanly in a pipeline, it just isn't incremental. Pick gzip/zlib/deflate for
 * unbounded streams.
 *
 * @example
 * ```ts
 * import { compressionStream } from '@myrialabs/zipkit';
 * await response.body
 *   .pipeThrough(compressionStream('gzip'))
 *   .pipeTo(writable);
 * ```
