poll_scheduler_log()/query_scheduler_resvals() tail the live scheduler
daemon's log (task 4.1's trace line) for each accepted injected resource,
with a bounded ~15s wait batched across all pending resources per poll
iteration (not N times the timeout). Reports MATCH / MISMATCH (both
values) / UNREACHABLE (timeout, distinct from mismatch), tracked in
SCHEDULER_OBSERVED/SCHEDULER_CHECK_RESULTS + scheduler-check-results.tsv.
Live-proven immune to bug-1579 (unlike the controller check): injecting a
host-attrs resource (cpuf) simultaneously produces a controller MISMATCH
and a scheduler MATCH, since this check reads task 4.1's trace log (written
once, at apply-time) rather than re-querying live state after the worker
disconnects.
