neural_reflect: condense its README section to the family's house style; remove the version tag from the module and the model manifest

neural_reflect: host a complete SUBLEQ machine (32-byte memory, fetch-execute loop) inside the interpreter, its memory accessed through indexed addressing

neural_reflect: interpret the SUBLEQ datapath from stored gates; index-read scaling, a compiler from family nets, self-reproduction, self-rewrite, and sequential-state programs

neural_reflect: universal netlist interpreter with indexed addressing, two banks, and a compiler from family nets

Add neural_reflect: a threshold interpreter whose state holds its own weights
