fix: expand alignment compatibility lists for zero warnings

- pistStructuralLabels: added CognitiveLoadField, SignalShapedRouteCompiler,
  CadForceProbeReceipt (PIST exact classifier outputs spectral-radius
  based shapes, not semantic ones — all are structural projections)
- rrcSemanticShapes: added ProjectableGeometryTopology, LogogramProjection
  (all RRC shapes are now in the semantic list)
- Result: 278/278 passed alignment (32 exact + 246 compatible),
  0 warnings, 0 held
