Add ZIP archive support to the node:zlib module through three classes and a set of helpers: - ZipEntry: a single archive member, with buffered reads (content()), bounded-memory streaming reads (contentIterator()), and create()/createStream() for building members. - ZipFile: random access to an archive backed by a file descriptor, reading members lazily without retaining their content and writing new members in place; opened with open()/openSync(). - ZipBuffer: a zero-copy, in-memory view over an archive already held in a Buffer. createZipArchive() serializes a sequence of entries into an archive byte stream, and setMaxZipContentSize() bounds the default in-memory decompression size. Every operation has both an asynchronous and a synchronous form.
