feat: Add math modules — stats, scale, epsilon, score, signal
Centralizes common math operations used across core/go-ai, core/go,
and core/mining into Poindexter as the math pillar (alongside Borg=data,
Enchantrix=encryption).

New modules:
- stats: Sum, Mean, Variance, StdDev, MinMax, IsUnderrepresented
- scale: Lerp, InverseLerp, Remap, RoundToN, Clamp, MinMaxScale
- epsilon: ApproxEqual, ApproxZero
- score: WeightedScore, Ratio, Delta, DeltaPercent
- signal: RampUp, SineWave, Oscillate, Noise (seeded RNG)

235 LOC implementation, 509 LOC tests, zero external deps, WASM-safe.
