Cause: live applies every pushed config through sched_init_config(),
whose plugin_config_update() runs each plugin's config_hook (the limit
plugin builds its limits there). The simulator seeded the limit plugin
only at bootstrap (sim_bootstrap_limit_plugin()); the core's CONFIG_PUSH
event loaded groups, resources and queues but never told the plugins,
so a limit added during a replay never existed in sim.
Fix: one shared fan-out, plugin_config_update_core(core, config), which
live's plugin_config_update() now delegates to. The core's CONFIG_PUSH
calls a driver-registered xce_core_config_cb_t after loading groups (live
order), keeping the core free of plugin.c; the simulator registers the
fan-out in sim_bootstrap_limit_plugin(). limit_update_config() reads the
honestly-typed plugin->core instead of casting plugin->sched, so the hook
is safe on the sim core; the hand-built plugin fixtures in
test_limit_plugin.c/test_repl_limit_table.c now set plugin->core as
plugin_register() does. test_sim_limit_config_push_parity.c covers it.
