- New fabric-bridge node: initiator mode reads local MXL flow and
transfers via Fabrics (RDMA/TCP); target mode receives remote data
and commits to local MXL flow writer
- Add set_mxl_instance/get_mxl_instance to Node base class
- CMake option DMF_BUILD_FABRICS=OFF by default (needs libfabric)
- Target publishes target_info in status for out-of-band exchange
- Initiator receives target_info via config parameter
