Reward function experiments: research v1.0.1

The experiment repository is now arpjw/reward-function.

This release updates the repository identity, canonical links, citation metadata, experiment-focused README and paper PDF/LaTeX. It preserves the prior paper-v1.0.0 release. The mathematical derivations, raw scientific inputs and measured results are unchanged. Public CPU reconstruction and private tensor/operational archive boundaries remain the same.

Contains the refreshed 26-page PDF and complete reviewed research archive. This is a publication/link maintenance revision, not a new experiment result.
