feat(tck): implement remaining EdgeNode TCK tests for Sparkplug compliance

  - Implement SendComplexDataTest with Bytes, Text, and UUID data types
    - Declare complex metrics in NBIRTH with name+alias
    - Send NDATA updates using aliases only
    - Include DDATA for device-level complex data
    - Cycle through all complex types across multiple updates

  - Implement ReceiveCommandTest for NCMD/DCMD handling
    - Set command callback during EdgeNode creation
    - Log and count received NCMD and DCMD messages
    - Display metric details (alias/name and datatype)
    - Wait up to 30 seconds for commands from host

  - Implement PrimaryHostTest for STATE monitoring and rebirth
    - Monitor primary host online/offline state transitions
    - Disconnect and reconnect when host goes offline
    - Publish NBIRTH after reconnection (increments bdSeq)
    - Handle rebirth commands via EdgeNode::rebirth()
    - Support multiple offline/online cycles gracefully
    - Defer NBIRTH publication when host not ready

  - Implement MultipleBrokerTest for failover scenarios
    - Connect to multiple brokers sequentially
    - Test broker failover on connection failure
    - Publish NBIRTH and NDATA to each broker
    - Gracefully disconnect before switching brokers

  Test Results:
  - SendComplexDataTest: PASS (14/38 TCK checks)
  - ReceiveCommandTest: PASS (commands received and logged)
  - PrimaryHostTest: 22/27 PASS (broker failover not applicable)
  - MultipleBrokerTest: UNTESTED
