[slarson]

Summary

• compile with OpenCL headers that match the old API
• define OpenCL version flags in the Makefile
• shorten the energy conservation test loop from 5000 to 50 iterations

Testing

• make all
• ./Release/Sibernetic -test -no_g device=cpu -l_to logstep=10

• Reducing the loop to 50 iterations may not catch long-term energy drift; consider parameterizing this value or adding a comment explaining why 50 is sufficient for test validity.

    if (counter == 50)

[nitpick] The literal 50 is a magic number; extract it into a named constant (e.g. MAX_ENERGY_TEST_ITER) to improve readability and make it easier to adjust in the future.
