feat(scheduler-core): enforce simulation isolation (task 11.3)

Browse source 
Three-layer regression guard (test_sim_isolation.c) proving sim.h/sim.c/
sim_loop.c hold no controller-facing client/cluster-config/capnp-socket
state: source-text scan, struct-body field scan, and nm(1) link-time
undefined-symbol audit of a new isolated sched_sim_isolation_lib target.

# Task 11.3 (scheduler-core spec, Req 5 AC 17): isolated compile target for
# the simulation driver's own files, consumed by
# testsuite/test_sim_isolation.c to prove at build time that sim.c/sim_loop.c
# reference zero controller-facing symbols (client/netio/xceapi/delay/idgen).
# Both files are compiled together into ONE archive -- task 11.2 added
# sim_loop.c as a sibling file to task 11.1's sim.c, and covering only one of
# them would repeat core.c's own siblings' (core_events.c/core_session.c/
# core_clock.c) never-mechanically-covered gap for the sim driver. Same
# "compiling to an object is enough, no real linking needed" rationale as
# sched_core_isolation_lib above.
