Module phenotype 

Phenotype construction — turning a TopologyGenome into a callable network.

PhenotypeBuilder abstracts how a genome becomes a network so a future CPPN/HyperNEAT builder is a new impl, not a trait change. The reference builder, InterpretedBuilder, produces an InterpretedPhenotype: a host-side feedforward evaluator built from bare Tensor<B, 2> arithmetic over the genome’s enabled connections in topological order — no Burn Module, no autodiff, no Recorder. NEAT phenotypes need only a forward pass, so skipping Burn’s Module (whose #[derive] needs a static field structure a data-defined topology cannot supply) costs nothing.

The interpreted seam (PhenotypeBuilder/Phenotype) evaluates one genome at a time. Its population-batched companion, BatchPhenotypeEvaluator, runs the whole population in one device-resident forward pass; the dense-padded DensePaddedEvaluator is the stock-Burn implementation.
