FluxExecutor submits jobs directly to Flux via its Python bindings rather than wrapping flux run as a subprocess. It is useful when running inside containers where standard MPI runners are unavailable. - New libensemble/executors/flux_executor.py with FluxExecutor and FluxTask - Conditionally import FluxExecutor in executors/__init__.py (graceful ImportError if flux-core bindings are not installed) - Append FluxExecutor unit tests to test_flux.py; tests skip automatically when flux-core Python bindings are not present
