`SparseSynapticMap<const N: usize>`

CSR-style sparse weight matrix for fixed neuron count N.

API	Role
`new` / `from_dense` / `from_adjacency`	Build
`get_row` / `get_weight` / `set_weight`	Access
`nnz` / `sparsity`	Density stats
`to_dense` / `to_gpu_arrays`	Export

SparseSynapticMapBuilder<N>:

Type	Role
`NeuronStateSnapshot`	Per-neuron adaptation / error tracking
`RoutingPolicy`	Score = base weight − adaptation penalty + error bonus; `should_activate`
`TelemetrySnapshot`	Deprecated alias of `NeuronStateSnapshot`

let score = policy.score(neuron, &snapshot, base_weight);
if policy.should_activate(score) { /* … */ }
