MAESTRO: Implement Group Chat integration tests (6.1-6.6)

- Add integration test infrastructure in group-chat-test-utils.ts
  - Helper functions for agent selection, response waiting, cleanup
  - Support for SKIP_INTEGRATION_TESTS environment variable

- Add 6 integration tests in group-chat.integration.test.ts
  - 6.1: Basic moderator response
  - 6.2: Two agents collaborate on addition task
  - 6.3: Agents reference chat log for context
  - 6.4: Moderator handles non-existent participant
  - 6.5: Chat log persists across restart
  - 6.6: Mixed agent types work together

- Add vitest.integration.config.ts for integration tests
  - 3 minute timeout per test
  - Sequential execution to avoid agent conflicts

- Add npm scripts: test:integration, test:integration:watch
