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.

/*
* test_sim_isolation.c - regression guard for task 11.3's Observable
* (scheduler-core spec, Req 5 AC 17, "Simulation isolation"): "a build-time
* or structural check confirms no controller-facing symbol is reachable
* from the simulation driver's compiled object" -- plus the AC's own
* "confirmed by the struct definition itself, not runtime checks alone"
* clause. Scope: sim.h + sim.c + sim_loop.c together (task 11.1 + task
* 11.2's sibling file) -- NOT a re-audit of core.c (task 4.1's own
* territory, test_core_isolation.c) and NOT plugin.c/builtin_fcfs.c (shared
* normal-mode infra, out of this task's boundary).
*
* Three layers, extending test_core_isolation.c's two-layer pattern (same
* genre: source-text scans of the real, current on-disk files, not a frozen
* snapshot):
*
* 1. Source-text scan of sim.h/sim.c/sim_loop.c: no #include of
* client.h/netio.h/xceapi.h/delay.h/idgen.h/xce/cluster.h; no call-site
* substring matching a symbol exported only by those libraries (the
* exact FORBIDDEN_SYMBOLS list test_core_isolation.c already
* established, reused verbatim here, not reinvented).
*
* 2. A structural check test_core_isolation.c has no equivalent of: Req 5
* AC 17 explicitly requires "the xce_sched_sim_driver_t shall contain
* no xcecli_ctx_t, no xce_cluster_config_t, no capnp socket" --
* enforced by the STRUCT DEFINITION ITSELF, not merely by absence of
* the type names anywhere in the file (sim.h's own boundary comment,
* just above the struct, legitimately NAMES xcecli_ctx_t and
* xce_cluster_config_t in prose while documenting this exact
* requirement -- see strip_c_comments()'s doc comment below for why
* that makes a naive whole-file scan wrong). This layer extracts ONLY
* the `typedef struct { ... } xce_sched_sim_driver_t;` body text and
* scans that narrower region for forbidden field types.
*
* 3. The literal build-time/link-time proof the Observable asks for, not
* achievable by a text scan alone: sim.c AND sim_loop.c together (not
* just one -- task 11.2 added sim_loop.c as a sibling file to task
* 11.1's sim.c, and repeating core.c's siblings' own "never
* mechanically covered" gap for the sim driver's own second file would
* be exactly the mistake this task exists to avoid) are compiled in
* isolation into their own static library (meson.build's
* sched_sim_isolation_lib, this test's XCE_SIM_LIB_PATH), and this test
* inspects that archive's UNDEFINED SYMBOL TABLE via nm(1) -- proving
* what the compiled code ACTUALLY calls, independent of what any
* header happens to transitively declare. Same "compile alone, inspect
* undefined symbols" technique and same rationale
* test_core_isolation.c's own header comment gives for why nm on a
* static_library() (not the full xce_scheduler executable, which links
* the whole monolithic libxce_dep and would prove nothing about this
* one translation unit).
*
* Deliberately NOT covered here: the wall-clock ban (FORBIDDEN_WALLCLOCK in
* test_core_isolation.c) -- that constraint is scoped to core.c/core.h
* specifically (Req 5 AC 3), not to driver-level code. sim.c's
* sim_set_virtual_clock() and sim_loop.c's sim_advance_virtual_clock() both
* legitimately call clock_gettime() to seed/advance the core's virtual-clock
* anchors from the driver side -- their own doc comments already explain why
* this does not violate core.c's isolation boundary. Applying
* FORBIDDEN_WALLCLOCK here would incorrectly fail on that legitimate,
* documented behavior.
