fix(scheduler): sim mode force-dispatched recorded decisions past live capacity (bug-1836, bug-1838)
User-reported: replaying a captured session dispatched 44 single-slot jobs
onto a 22-slot host. Root cause traced through two layers:

- bug-1836: sim_reconcile_unaccounted_jobs() (the "Recorded-Decision
  Reconciliation" backstop) force-applied any recorded DISPATCH decision
  it found, with zero live capacity check. Added
  sim_reconciled_alloc_fits_capacity(), reusing the same
  sched_check_host_satisfy()/sched_check_shared_satisfy() admission checks
  the live picker/allocator path already uses.

- bug-1838: even with that gate, reconciliation still preempted every
  freshly-PEND job before the live picker/allocator got a turn each round
  -- unnecessary now that scheduler-sim-live-allocation gave sim mode the
  same real, capacity-checked picker/allocator threads normal mode uses.
  Narrowed reconciliation's trigger back to JOB_IS_RUN-only (undoing a
  2026-09-11 widening whose own justification no longer holds), so a
  freshly-pushed job now always flows through the same live, verified
  decision path as normal mode. Reconciliation now only ever fires for a
  job already RUN from before the replay's own observation window --
  the one case structurally invisible to the live picker.

Also logged (bug-1837, not fixed here, needs its own design decision):
sim_reconcile_unaccounted_jobs() calls a picker's on_dispatch() hook from
the driver thread instead of the allocator thread plugin.h documents it
belonging to -- currently inert since the only real picker plugin happens
to lock internally, but not contract-safe for a future lock-free one.

Fixing bug-1838 required re-examining every test exercising the old
PEND-inclusive trigger; several needed their fixtures corrected to
register a real worker (harmless before any capacity check existed), and
others needed their actual intent re-derived and their assertions
inverted or restated now that a PEND job is never eligible for
reconciliation. Dated correction notes added in place to the
scheduler-sim-eager-reconciliation spec, matching its own existing
2026-09-11 correction-note precedent.

Verified: full scheduler suite 85/85, independently re-confirmed by
running the four most affected binaries directly.

/*
* test_repl_step_verbosity.c - contract test for the interactive simulation
* REPL's Event Echo Preamble Deduplicator component
* (scheduler-sim-step-verbosity spec, task 1.1, Requirements 1 and 2): the
* "[sim] t=<ns> (<ISO8601>) session=<N>" preamble line
* repl_print_event_summary() (repl_break.c) prints immediately before an
* echoed event's own content line should print once per distinct
* (rendered second-granularity timestamp, displayed session) run of
* consecutive echoed events, not once per event -- leaving which events are
* echoed, their own content, and their ordering completely unchanged.
*
* Split into its own file from the start (rather than appended to the
* sibling test_repl_event_echo.c) -- design.md's File Structure Plan flags
* that file's ~1000-line split trigger: it was already 705 lines
* (scheduler-sim-repl-verbosity's Event Echo Gate tests) before this
* feature began, and this task's six behavioral cases plus their own
* preamble-construction helper would have pushed it well past that
* threshold. Following this file family's established convention (see
* test_repl_event_echo.c's own header comment on why IT split out of
* test_repl_execution_control.c, and test_repl_round_rollup.c before it),
* this file duplicates -- rather than shares via a new header -- the
* pre-existing static fixture helpers it needs from test_repl_event_echo.c.
*
* Fixture strategy and white-box #include set: identical to
* test_repl_event_echo.c/test_repl_round_rollup.c/
* test_repl_execution_control.c (see those files' own header comments) --
* this file exercises the same real sched_sim_driver_run() end-to-end,
* forked-child, real-stdout-capture technique. Discrete-simulation
* determinism note (research.md's own key finding, load-bearing for every
* test below): `child_run_repl_and_exit()` sets args.sim_speed = 0, which
* sim_set_virtual_clock() (sim.c) stores as core.speed_num == 0; with
* speed_num == 0, xce_core_now()'s (core_clock.c) `elapsed * num / den` term
* is always exactly zero, so xce_core_now() returns EXACTLY the raw
* nanosecond `ts` value most recently passed to sim_advance_virtual_clock()
* (sim_loop.c) for the event just decoded -- i.e. exactly the `ts` argument
* each append_*_event() helper below is given, with no wall-clock jitter.
* This is what makes it possible to construct exact, reproducible raw-ns
* values below (including deliberately far-apart raw values that still
* round to the identical displayed second) rather than merely hoping two
* events land in the same second.
*
* bug-1595 jobid-safety discipline: NONE of this file's fixtures push,
* mutate, or reference any job or jobid at all -- same discipline
* test_repl_event_echo.c's own header comment documents, for the same
* reason (every event used below, QUEUE_UPDATE/WORKERS_PUSH, is deliberately
* job-free).
*
* THIS TASK (1.1) IS RED-PHASE ONLY: the preamble-dedup cache/short-circuit
* under test does not exist yet in repl_print_event_summary() (repl_break.c)
* today -- that function unconditionally builds and prints the preamble on
* every single call, with no reference to any "last printed" state on
* xce_sched_repl_state_s (task 1.2, a separate later task, adds both the
* cache fields and the short-circuit). Every symbol this file references
* already exists today, so every test below builds and links cleanly but
* FAILS certain of its own runtime assertions -- specifically, every
* assertion that a SECOND same-context event's preamble is ABSENT. Verified
* concretely (not assumed) against a real incremental ASAN build before
* this task was reported done -- see this task's own Status Report.
*
* Assumed output contract this file pins (matches design.md's Event Echo
* Preamble Deduplicator component and test_repl_event_echo.c's own
* "Assumed output contract" precedent):
* - repl_print_event_summary() prints "[sim] t=<ns> (<ISO8601>)
* session=<N>\n" where <ns> is the exact raw nanosecond value
* xce_core_now() returns for that event (see the determinism note
* above), <ISO8601> is that same value rendered via
* repl_format_ts_human() to second granularity, and <N> is
* rs->session_count + 1 at the moment the event is echoed.
* - TARGET (post task 1.2) behavior this file's RED assertions pin: that
* preamble line is printed only when <ISO8601> or <N> differs from the
* immediately preceding ECHOED event's own printed <ISO8601>/<N> (or
* when there is no preceding echoed event this session) -- never based
* on the raw <ns> value, which may legitimately differ between two
* events sharing the same displayed <ISO8601>/<N> (Requirement 1.3).
* - An event's own content line (the existing "[sim] event: ..." switch
* in repl_print_event_summary()) is unaffected either way -- always
* printed exactly as today, in the same relative order (Requirement
* 1.4, 2.2).
* - Tests use strstr()/pointer-order comparisons on captured real stdout,
* the same technique test_repl_event_echo.c's own tests establish.
