allaun 04546db009 fix: CharPoly Newton solver — correct Horner evaluation
Two bugs: (1) evalPoly started with x instead of one (leading coeff),
giving degree n+1 polynomial. (2) evalDeriv used (n-i)*ci instead of
(n-1-i)*ci, off by one. Both coefficients used ofRawInt (wrong scale)
instead of ofInt (correct Q16_16 scale).

Result: spectral radius of 2x2 identity now 65408 (~99.8% of 65536).
Remaining error is Q16_16 underflow for double root (lambda-1)^2.
