Trap: createWriteStream().end() looks sufficient before spawning a downloaded binary because its callback follows finish, but finish does not guarantee the file descriptor is closed and Linux can raise ETXTBSY. Fix: streamDecompressToFile() uses openSync/short-write-safe writeSync/closeSync, preserving the first write or stream error over close failure. Synchronous close makes compressed downloads race-free before execution.
