feat(scheduler-core): implement simulation-mode startup (task 11.1)

Browse source 
Add sim.h/sim.c implementing AC 13 steps 1-4: open+validate ReplayHeader,
locate the most recent SnapshotEntry at/before --sim-start-ts, load it via
xce_sched_core_load_snapshot(), and set the virtual clock anchors. Wire
all seven simulation CLI flags into main.c's task-5.2 mode-selection
branch. Event loop itself (step 5) deferred to task 11.2. Fixes two real
bugs found during TDD: a SnapshotEntry_get_ts() use-after-free and a
pend_updates NULL-deref in xce_sched_core_fini() for bare-core callers.
27/27 scheduler suite green, full project build clean.

# Contract test for simulation-mode startup (scheduler-core spec, task 11.1,
# Req 5 AC 13): opening and validating the replay file (first message must
# be ReplayHeader, first data message must be SnapshotEntry), locating the
# most recent SnapshotEntry at or before --sim-start-ts, loading it via the
# real xce_sched_core_load_snapshot(), and setting the virtual clock's
# anchors from the loaded snapshot's timestamp and requested speed. Same
# white-box #include pattern as sched_snapshot_save_load_test (../src/core.c,
# ../src/core_clock.c, ../src/snapshot.c, ../src/snapshot_wire.c,
# ../src/snapshot_load.c) PLUS ../src/recording.c (used only to build real
# `.replay` fixtures via sched_record_start()/sched_record_stop(), not under
# test here) PLUS the new ../src/sim.c under test. No driver.c/plugin.c/
# core_events.c/core_session.c/decision.c: this task stops at "ready-to-run"
# (task 11.2 owns the event loop), so no real scheduling session is ever
# driven.
