Read-only InputStream backed by a ByteBuffer (typically a MappedByteBuffer from PakManager.mapWhole). Reads advance the buffer's position; mark/reset is supported via the buffer's mark()/reset().

Used by PakManager.openInputStream to expose the pak mmap zero-copy path through the standard InputStream interface — every Kotlin asset reader that already calls openInputStream (GLXFFileLoader, LocalizedAssetResolver, etc.) gets the win without changes.

The buffer is stored by reference, so the underlying mmap region (kept alive by FileChannel's internal cleaner on the MappedByteBuffer) survives until this stream is GC'd.
