test(resreq-maxtasks-wiring): verify ingest wiring parity and no-regression

Browse source 
Adds test_maxtasks_wiring_ingest.c proving: (1) fresh ingest's
dispatched primary resreq reflects a real multi-task job's requested
count via the real core_build_job()/JOBS_PUSH path; (2) fresh ingest
and snapshot-restore ingest derive the identical task count for an
equivalent job, asserted both against expected constants and via
direct cross-comparison (Requirement 5.6); (3) a single-task job
reaches identical real host-selection/allocation behavior through the
live allocator dispatch chain, proving the feature is a true no-op
for maxTasks==1 (Requirements 3.1/3.2). No production code changed --
tasks 2.1/2.2 already wired the fix; this adds cross-call-site and
behavioral proof neither of those isolated tests attempted.
