react-native-gzip

native-seam only — the real upstream 31-line wrapper (`Gzip.inflate(base64)` / `Gzip.deflate(data)` with a LINKING_ERROR fallback proxy) runs from the bundle. sootsim registers the Gzip TurboModule backed by the browser's CompressionStream/DecompressionStream for real gzip round-trips (matches upstream's iOS Gzip.mm contract).
