    Class ConsensusEngine

    Consensus engine for multi-agent decision making.

    const engine = new ConsensusEngine({ defaultTimeout: 30000 });
    const proposalResult = await engine.propose({
      title: 'Use microservices architecture',
      description: 'Proposal to adopt microservices',
      algorithm: 'supermajority',
    });
    if (proposalResult.ok) {
      await engine.vote(proposalResult.value, 'agent-1', {
        decision: 'approve',
        confidence: 0.9,
        reasoning: 'Good for scalability',
      });
