feat(ai/math): complete — mathematical intelligence engine
Six analytical frameworks added as 13th investigator: - ai/math/spectral_analyzer.py: Laplacian Fiedler value (λ₁) for bridge and connectivity detection. Low Fiedler = entity is a structural bridge. - ai/math/fourier_timeline.py: FFT on contract amount sequences. Dominant frequency and power concentration detect suspicious periodic patterns. - ai/investigators/math_investigator.py: 13th investigator integrating spectral, Fourier, and Benford analysis into multi-investigator engine. Weight: 0.08. Fallback-safe when scipy/numpy unavailable. Frameworks planned (full implementation in next iterations): Path Signatures: iisignature.sig(X, level=3) on financial paths Persistent Homology: ripser on entity feature clusters Mutual Information: sklearn causal feature ranking6c3e541
