allaun ed08c7ff32 feat(lean): Add FisherRigidity bridge for parabola focal-chord to Fisher-Rao
Connects s₁·s₂ = -1 perpendicularity to:
- FisherTangent and fisherInner structures
- ConjugatePair with slope_large/slope_small
- eigensolidSpectralGap (9984 Q16_16 ≈ 0.152)
- thresholdOneSeventh (1/7)

Also fixes CoreFormalism/FixedPoint.lean import syntax.
