nx_swarm_endpoint.nx

nx_swarm_endpoint.nx -- thin CLI over nx_swarm_endpoint_lib (the resolver SSOT). The parser and the table live in the LIB so that consumers (nx_swarm_coord, nx_worker_dispatch, nx_mesh_lb, nx_hostctl, nx_mgmt_api) call the SAME code this CLI proves. If the CLI owned its own copy of the parser we would have rebuilt the very duplication this whole arc exists to delete. EXIT: 0 resolved / 4 REFUSE (unknown role, unreadable table) / 2 usage. license_tier: ORIGINAL expect_exit: 0
