/**
 * Pure-JS drop-in replacement for `hysnappy`.
 *
 * `hysnappy`'s `snappyUncompressor()` eagerly compiles a WASM module
 * (`new WebAssembly.Module(byteArray)`) — and `hyparquet-compressors`
 * instantiates it at module top level (`SNAPPY: snappyUncompressor()`).
 * Cloudflare's `workerd` forbids compiling WebAssembly from a runtime buffer
 * (WASM must be a bundled module import), so any Worker bundle that imports
 * `icebird` (→ `hyparquet-compressors`) fails to start with
 * `CompileError: Wasm code generation disallowed by embedder`.
 *
 * `icebird`'s append path never actually decompresses a snappy data file — it
 * only reads gzipped `metadata.json` and Avro manifests — so the snappy
 * decompressor is instantiated but never invoked. This shim swaps the WASM
 * codec for `hyparquet`'s pure-JS snappy decompressor (a vendored snappyjs),
 * keeping the exact `hysnappy` API surface so `hyparquet-compressors` is
 * unaware of the swap. Wired in via a build-time `hysnappy` alias.
 *
 * See `docs/plans/2026-05-22-icebird-ingest-writer-spike.md` (section e).
