fix(lib): a malformed select in a resreq fails the parse instead of being dropped (bug-1887)
The primary_resreq action ignored parse_resreq_primary()'s result, so a
primary whose select (or rusage) clause failed to parse was accepted
without that clause: select[type==] or select[mem>] matched every host.
A malformed clause now fails the whole resreq, and parse_resreq() returns
the clause's own message.

A select naming an unregistered resource is still dropped, not an
error: parse_select() reports it as -ENOENT (new select_context_t
.unknown_resource) and the action lets it pass, because jobs rely on it
-- the scheduler's own "type == any" default among them when no "type"
resource is registered (making it fatal failed 36 scheduler suites).

Test: test_resreq_primary_select_error_fails_parse RED before (all
accepted), GREEN after.

fix(scheduler): a batch replay exits 0 under LeakSanitizer (bug-1884, part 6)
- kill_sched_resval() (every resource-value array's item killer) frees
  the value, not only a string's buffer: each replaced or torn-down value
  leaked its struct, including every WORKERS_PUSH value update.
- put_resvals() shares the value it creates with later entries for the
  same index in one call; it created a second one that replaced (and now
  freed) the first while still writing through it.
- JOB_UPDATE and the duplicate-JOBS_PUSH path kill_resreq() the old parsed
  resreq, and free the rejected job's schedobj (xce_core_free_schedobj(),
  exported from core.c), instead of freeing only the containers.
- The previous attempt's (or ALTER alternative's) pend reason is freed when
  a new one replaces it.
- kill_resreq_ctx() frees the parser context's error message, and the
  primary-resreq PEG action frees an earlier primary's message first.
- write_snapshot_entry() frees the snapshot it builds (config and resource
  objects detached, they are the core's); the save side strdup()s its
  strings so the generated free_SnapshotData() applies.

Test: test_cli_batch_replay_exits_clean_under_leak_detection
(test_sim_discrete_clock.c) runs the real binary on a two-session fixture
with detect_leaks=1 and requires exit 0: RED before (exit 1), GREEN now.
All nine HA-soak recordings replay with exit 0 and no LeakSanitizer report.

fix(apiserver): reject a malformed rusage[] at job submit (bug-1744)
Gitea #47: `xcecli jobs submit -R "rusage[mem=100000000a0]"` was accepted
with a normal "Job <...> is submitted" reply. The apiserver only
length-checked resreq; the real PEG grammar ran later, asynchronously, in
the scheduler's core_build_job(), which logged a server-side WARN and
dropped the job -- it then sat PEND forever with no sign of why.

- libxce: xce_check_rusage_syntax(resreq, &errmsg) runs parse_rusage() on
  every rusage[...] clause (extracted the way section.peg does: up to the
  first ']'), so primary, compound and alternative requests are all
  covered. No resource manager needed, so select[]/order[] resource names
  are still only checked by the scheduler (the documented scope).
- apiserver/backend: ValidateResreqSyntax() cgo wrapper (resreq_check.go);
  the !cgo stub returns nil (no job can be submitted without CGO anyway).
- controllers/jobs.go preCheckJobRequest(): calls it after the length
  check via a package var, so a malformed request is refused up front.

Tests: lib test_check_rusage_syntax (RED before: the reported input was
accepted) and backend TestValidateResreqSyntax (RED before) through the
real grammar; controllers TestPreCheckJobRequest_RejectsMalformedResreq
checks the call site with an injected validator (written with the call
site, so no separate RED). libxce, apiserver backend (cgo) and controllers
tests pass. apiserver/middleware TestLoadJobs fails here and on the
baseline alike: it needs a live apiserver on :8080.

refactor(scheduler): move job-total limit computation to the limit plugin (bug-1790)
bug-1790's fix worked but put limit-plugin-specific logic in the wrong
place: seqjob_prepare_allocation()/parjob_prepare_allocation() (the
allocator plugins) unconditionally pre-computed a job-wide total for
every per-host resource in the job's rusages, "just in case" some
global limit needed one. That's the allocator plugins' concern leaking
into limit evaluation -- duplicated across both allocators (a third
would need it too), and wasteful (computed for resources no limit
actually references).

Moved ownership to sched_fill_limit_requests() (resource.c), called
once centrally from plugin_prepare_allocation() regardless of which
allocator ran:

- Removed calc_wanted_host_resval_job_totals() and its calls from both
  allocator plugins entirely.
- Added calc_wanted_job_total_resval() (resreq.c): an on-demand,
  single-resource lookup by name (no resmgr/key_find needed -- the
  caller already has the resolved xce_resource_t), computing the same
  job-wide-total formula only for the one (scope, underlying-resource)
  combination that needs it -- a GLOBAL limit on a per-host resource.
  The other three combinations are unchanged, still reading straight
  out of alloc_req.
- sched_fill_limit_requests() gains rusages/nhosts/nslots parameters
  back (a genuine need this time, not a re-added unused one).
  plugin.c's two call sites pass obj->u.primary->resreq->rusages
  (NULL for COMPOUND/ALTER, matching this codebase's existing scope
  convention for those tags) and ctx->nhosts/ctx->nslots.

All 23 testsuite link-satisfying stubs mechanically updated. Removed
the two allocator-level regression tests from the first pass (the
behavior they proved no longer exists by design); rewrote
test_fill_limit_requests_global_limit_on_host_resource_reads_host to
exercise the new on-demand path directly, nslots=3 to prove the job's
WHOLE total is used.

Full xce-build.sh all asan --incremental: 94/94 Ok, zero regressions.
Live re-verified against the same ug1_global_mem deploy/scenario:
byte-identical scheduler trace to the pre-refactor result, confirming
behavior-preserving.

fix(scheduler): populate job-wide total want for per-host resources during global phase (bug-1790)
Closes the gap bug-1789 explicitly carved out: a GLOBAL limit built on a
per-host resource other than "slots" (e.g. a future absolute global mem
cap) needs ctx->alloc_req.host to carry that resource's job-wide total
want during the global phase, but only "slots" ever got that treatment
(via seqjob/parjob_prepare_allocation()'s own unconditional store).

Adds calc_wanted_host_resval_job_totals() (resreq.c), sharing its loop
body with calc_wanted_global_resvals() via a new static helper
parameterized only by which XCE_RESF_GLOBAL direction to match -- it
computes the SAME job-wide-total formulas (PER_TASK: value*nslots, PER_JOB:
value, PER_HOST: value*nhosts) for non-global resources instead of global
ones. seqjob/parjob_prepare_allocation()'s global-phase branch now calls
it into ctx->alloc_req.host alongside the existing calc_wanted_global_
resvals() call into .shared.

Safety was traced, not assumed: plugin_prepare_allocation() only resets
.host at the top of a per-host call, never during the global phase, and
sched_fill_limit_requests() for glimits reads .host later in the SAME
global-phase invocation -- transferring the value into the limit's
permanent .shared record before any later per-host call ever resets
.host. An earlier candidate fix (reusing calc_wanted_host_resvals()
directly) was rejected during design: its PER_HOST formula and, for
parjob, its per-bucket nslots don't give a job-wide total.

New regression tests in test_seqjob_allocator.c/test_parjob_
combinatorial.c prove a non-"slots" per-host resource ("mem") now gets
correctly populated; parjob's test uses maxTasks=3 specifically to prove
the formula uses the job's whole nslots, not a bucket's share.

Full suite (xce-build.sh all asan --incremental): 92/94, both failures
pre-existing and unrelated (bug-1762, bug-1733's already-documented
xcealloc.c leak). Not live-verified -- no limits.yaml entry exercises
this path yet.

feat(resreq-maxtasks-wiring): add task-count derivation helper
Adds apply_job_task_count() to overwrite a standalone primary resreq's
minTasks/maxTasks with a job's real requested task count, no-op for
COMPOUND/ALTER nested primaries, with a defensive min>max clamp.
Closes the gap that lets scheduler-allocation's multi-host allocator
ever be reached (bug-1770). Wiring at live ingest call sites follows
in subsequent tasks.

feat(scheduler-allocation): add resreq fingerprinting for the cache
Adds rusage_hash to xce_primary_resreq_t (computed once by
parse_resreq_primary() via a new hash_rusages() helper, hashing
rusage content rather than raw struct bytes since resname is a
non-interned strdup'd pointer), the xce_resreq_fingerprint_t value
type, and resreq_fp on xce_primary_schedobj_t, populated once at real
job-ingest time in core_build_primary_schedobj().

Task 1.2 (scheduler-allocation spec). Requirement 7.1.

b38babb7d6 feat: implement Phase 4d const-fold transform for select AST
Adds sel_const_fold_pass() — a single-pass bottom-up const-fold that
runs after the Phase 4c flatten loop in parse_select():

  4d-1  EQ/NE with either operand SEL_ANY → SEL_TRUE / SEL_FALSE
        (checks both child slots — commutativity sort makes SEL_ANY
        position non-deterministic after makeSelectNode interning)
  4d-2  Identity laws: TRUE&&X→X, X&&TRUE→X, FALSE||X→X, X||FALSE→X
  4d-3  Annihilation laws: FALSE&&X→FALSE, TRUE||X→TRUE (symmetric)
  4d-4  Complement laws: !TRUE→FALSE, !FALSE→TRUE

Memory semantics:
  level==0 (API server): frees orphaned nodes via free_select_node /
    sel_free_tree; OOM from makeSelectNode returns original node safely
  level>0  (CSE/scheduler): never manually frees; annihilation folds
    return the already-interned left/right singleton directly (no
    redundant makeSelectNode call); OOM guard unconditional so CSE
    mode also degrades gracefully instead of returning NULL

9 new TDD tests added to test_select.c (RED→GREEN verified).
All 166 tests pass (157 prior + 9 Phase 4d).
