graph_modularity — CONNGRAPH `stats` op

• Data kinds: conn_graph × labels → measurement

• Call: import fullseye as fs; fs.ledger.graph_modularity(W: 'Any', labels: 'Any') -> 'float' (to call the implementation directly, import conngraph; conngraph.graph_modularity(W: 'Any', labels: 'Any') -> 'float'; from the registry, opsconngraph.get("graph_modularity"))

有向・重みつきモジュラリティ Q(Leicht–Newman 2008)。

Q = (1/m) Σ_ij (W_ij − k_i^out k_j^in / m) δ(c_i, c_j)、m = Σ W。全ノードが

1 つの群なら厳密に 0。対角(自己結合)は落とす。重みは非負であること。
