Brandon Schneider 539e29057f feat(lean): add TreeDIAT prototype to PistSimulation.lean ... TreeDIAT = Tree-to-Shell Coordinate Transform, enabling tree-structured search traces to participate in PIST spectral refinement alongside integer-shell (DIAT) data. Components: - TreeNode inductive type (binary tree with Nat labels) - treeMetrics: O(n) extraction of depth, leafCount, nodeCount, maxLabel - TreeDIAT structure: feature vector packed into Q16_16 space - treeDIATEmbeddingScore: heuristic bushy=embeddable, stringy=not - treeDIATToChaosState: project tree features into 3D chaos-game space - treeSequenceRegime: classify tree sequences by Kruskal-bound proximity - 14 #eval! witnesses on bushy/balanced/stringy fixtures Build: lake build Semantics.PistSimulation = 3309 jobs green.
