Integration with BaseAgent

// Before: No AgentDB integration
const agent = new TestGeneratorAgent({
  type: 'test-generator',
  capabilities: [...],
  context: {...},
  memoryStore: swarmMemoryManager,
  eventBus: eventBus
});

// After: With AgentDB integration (optional)
const agent = new TestGeneratorAgent({
  type: 'test-generator',
  capabilities: [...],
  context: {...},
  memoryStore: swarmMemoryManager,
  eventBus: eventBus,

  // AgentDB configuration (opt-in)
  agentDBConfig: {
    dbPath: '.agentdb/test-generator.db',

    syncPort: 4433,
    syncPeers: ['peer1:4433', 'peer2:4433'],
    enableLearning: true,
    enableReasoning: true,
    quantizationType: 'scalar'
