SDK: Overall review comments

We tried running the SDK as is and have some comments/ feedback on specific samples. Creating an issue so we can discuss this.

cllayerinfo - No Output from the sample

nbodycpp - Passes but animation does not close
conwaycpp - Passes but animation does not close

saxpy - Fails with:
Verification failed! -9127.552734 != -9127.553711 at index 1
Error: CL_INVALID_VALUE

saxpycpp - Fails with:
Error: Verification FAILED!

For the first two tests, we should perhaps improve the sample to provide meaningful output and to exit cleanly. In general, interested in checking if these samples behave the same on other implementations as well.

Rest of the samples look okay on initial review / run.

General comment that it would be useful for samples to log something to stdout if everything ran successfully,.

Run the named samples cllayerinfo, nbodycpp, conwaycpp, saxpy, and saxpycpp to reproduce the reported output, animation, verification, and CL_INVALID_VALUE issues. Compare behavior on other implementations if available; done means the affected samples produce meaningful success output, exit cleanly, and no longer report the listed failures.
