Rewires main.c's live scheduling loop onto the new core-driven architecture: xce_sched_driver_translate_pending_events() (task 5.1) -> xce_core_begin_session() -> plugin_begin_session()+sched_account_jobs() -> xce_core_signal_go() -> decision-drain via the registered xce_core_decision_cb_t -> plugin_end_session() -> xce_core_end_session(), all in the new exported xce_sched_driver_run_normal_mode_round() (driver.c), replacing the old inline sched_update()+sched_begin_session() +sched_go()+switch+sched_end_session() sequence. xce_core_go() (task 4.4) is split into xce_core_begin_session()/ xce_core_signal_go() -- a pure decomposition (xce_core_go() itself is now defined in terms of both, task 4.4's approved test suite passes unmodified) -- specifically so the driver can interleave plugin_begin_session()/sched_account_jobs() in the exact safety-critical window task 4.4 deliberately excluded from pure-core scope: after the resval reset, strictly before the picker thread is signaled. This is empirically proven by test_driver_session_ordering.c via real cross-thread happens-before assertions, not just documented. xce_sched_driver_on_decision() is the new registered callback: DISPATCH/PEND forward to the existing sched_publish_dispatch()/ sched_publish_pend_reason(); PREEMPT fails loudly (-ENOSYS, logged) since no xcecli_preempt() client API exists and nothing in the live allocator produces one yet (scheduler-preemption's territory). Adds a --sim CLI flag (parse-only, loud not-yet-implemented failure, since SimDriver is Phase 3).
