The terminal.Stream next/nextSlice functions can now no longer fail. All prior failure modes were fully isolated in the handler `vt` callbacks. As such, vt callbacks are now required to not return an error and handle their own errors somehow. Allowing streams to be fallible before was an incorrect design. It caused problematic scenarios like in `nextSlice` early terminating processing due to handler errors. This should not be possible. There is no safe way to bubble up vt errors through the stream because if nextSlice is called and multiple errors are returned, we can't coalesce them. We could modify that to return a partial result but its just more work for stream that is unnecessary. The handler can do all of this. This work was discovered due to cleanups to prepare for more C APIs. Less errors make C APIs easier to implement! And, it helps clean up our Zig, too.
