Resolves #56

Replace broken error_callback=RAISE pattern with result collection and
r.get() after pool.join(). The RAISE callback ran in a Pool helper thread,
so raising there killed the thread silently while pool.join() returned
normally—causing the pipeline to continue with missing or corrupt output
files from failed workers.

Now any worker exception is re-raised in the main process, killing the
pipeline immediately.
