feat: add RuntimeStatusStar and ACP integration tests

- Add RuntimeStatusStar ABP plugin exposing runtime internal state
- Add ACP echo server fixture for testing
- Add ACP integration tests (TCP/Unix socket connectivity)
- Update orchestrator to auto-register RuntimeStatusStar
- Update tests to account for auto-registered star
