The native adaptive install: chunks fetched in parallel through the fetch core in first-use order; single-use chunks are written at their part's offset into the file's staging file, shared chunks are kept in a budgeted cache (furthest-next-use eviction, refetch later), and every file is SHA-1 checked, synced and atomically renamed with the bounded writer's rules. New JNI export nativeStream.
