15 tests drive the real parjob plugin through job_alloc_fn: success,
short shared, pending on hosts, mid-plan rollback, task counts 0/1,
missing inputs, six OOM steps with their debits, COMPOUND. Values the
runner changes on purpose sit in *_today tests.
Spec: the task showed that parjob records host reasons only for a bucket
search's first rejected candidate (the rejected host's request stays in
alloc_req.host and the host iterator pre-filters later hosts against
it). Decision: the runner clears alloc_req.host before every candidate,
for both allocators, so every short host gets its reasons (Req 3.6/3.7);
publishing reasons only when they change is a follow-up.

12 tests drive the real seqjob plugin through job_alloc_fn and record
today's results, reasons and debits, with switch-stable OOM injection
(sched_make_allocs stub, --wrap of make_host_alloc/make_job_alloc).
Assertions the runner changes on purpose sit in *_today tests.
The characterization showed bug-1893's real effect: vget() returns 0 on
success, so the shared-reason loop (rc <= 0 skip) never records a shared
NO_RESOURCE reason. Bug record and spec wording corrected; the runner
skips only on rc < 0.

Requirements reviewed and revised (seqjob per-bucket reset, nslots/nhosts,
bug-1893 fix in the runner), design and 11-task plan generated and reviewed.
bug-1892: unsatisfy_() reads index-keyed uncommitted amounts by position.
bug-1893: allocators' shared pend-reason loop reads past the unmet list.
