Defines xce_alloc_plan_t (partition of a job's task count into
per-host slot buckets), xce_alloc_plan_iter_t, and xce_host_iter_t
(init/next/fini vtables, stack-allocate-then-init-in-place convention
matching sched_ctx_init) as reusable abstractions any allocator can
adopt. Proven usable by a trivial no-op reference implementation and
a fresh-per-bucket host_iter composition test, no allocator wired in
yet.
Task 1.1 (scheduler-allocation spec). Requirements 2.1, 3.1.

5.5 (Req 6 / G-5): the JOB_RUSAGE notify path called the plugin but never
stored the usage data — xce_sched_job_t had no rusage field (UB-6.1 unmet).
- Add xce_job_rusages_t* rusages to xce_sched_job_t.
- New sched_apply_job_rusage() stores the report ON the job (ownership
transferred), replacing any prior via free_JobRusages_ptr; -ENOENT unknown,
-EINVAL NULL. Dequeue NULLs the request pointer on success; kill_sched_job
releases job->rusages.
5.8 (G-3): sched_pend_update_killer left five new-op payloads on empty
break cases — a per-message leak since ownership is transferred on enqueue.
- Free each with the exact generated deep-freer: free_QueueConf_ptr,
free_Resource_ptr[], free_ResourceVal_ptr[], free_ResValList_ptr,
free_JobRusages_ptr. Safe: handlers nullify on enqueue, makeResource copies
via makeInstance, dequeue copies values (no aliasing).
Tests: sched_job_update_test 7/7 (3 update + 4 rusage), regression
sched_test 15/15, ASAN clean (no bad-free/double-free).

- Fix issue to xce_get() api cause client side crash
- add parse resreq section
- add rusage parser
- parse resreq with basic support alternative & compound, still miss select
