feat(scheduler-sim-decision-trace): wire the trace commands into the REPL

Browse source 
Task 5.2: trace is routed with the raw line and info trace through info;
help gains a Trace section; set output rejects open trace files; quit
and EOF shut tracing down; the continue-mode rollup reports a traced
round on its own; repl.h gains the interactive-only trace gates. The
baseline transcript changes only in the help and info-usage lines.

/*
* Decision trace gates (scheduler-sim-decision-trace spec, task 5.2;
* design.md "SimIntegration"; Requirements 7.1-7.3, 11.3). The entry
* points live in repl_trace_emit.c and are declared here, like the
* xce_repl_on_* hooks above, so this header stays self-contained. Each
* gate forwards only when the REPL is interactive, so a non-interactive
* simulation never publishes trace settings or prints a trace (11.3):
* - xce_repl_trace_session_begin: after a successful core begin-session,
* before reconciliation; makes the next settings current and
* publishes them to the scheduling core.
* - xce_repl_trace_session_end: after the decision stream ends;
* withdraws the published settings.
* - xce_repl_check_trace: a decision carrying a trace record, after the
* echo gate and before the breakpoint check; takes d->trace.
* - xce_repl_check_trace_only: an XCE_DECISION_TRACE decision (a traced
* selection with no decision), handled before anything else.
