Function variableElimination

variableElimination(
    factors: Factor[],
    query: string,
    evidence: Evidence,
): Map<number, number>
Variable Elimination for exact inference in Bayesian networks.

Computes P(query | evidence) by:
1. Reducing all factors by evidence
2. Eliminating non-query, non-evidence variables
3. Multiplying remaining factors
4. Normalizing
Parameters
- factors: Factor[]
  — initial factors (CPTs converted to factor form)
- query: string
  — variable to compute posterior for
- evidence: Evidence
  — observed variable values
Returns Map<number, number>
posterior distribution P(query=val | evidence)
