Fix two catastrophically heavy workloads found running the real campaign

Browse Source

The full 360-trial campaign was launched, then killed after 4h39m of
CPU time with zero trials completed -- still stuck on the very first
touch of the very first trial.

Root cause, quantified from the workload's own source, not estimated:
RUN-CHAOS5 (workload-5.4th) is 1000000 0 DO CHAOS-FIELD CHAOS-RIPPLE
LOOP, multiplying out to ~2.4 trillion word executions for one call --
~495 days at the observed rate. Never designed to be called to
completion as a single touch in a repeatedly-birthed worker.

A second problem found computing the fix rather than discovering it
mid-run again: workload-1.4th's own birth-time self-execution (20
SQUARE-WAVE + 1500 SQUARE-BURST + 100000x MICRO-BURST, all three run
automatically at capsule load) sums to ~875 million words -- ~4.3
hours just to birth one worker -- and worker index 1 always maps to
it in heterogeneous mode, landing in half the campaign's cells
regardless of concurrency level.

Fix: two new capsules, workload-1-lite.4th and workload-5-lite.4th,
carrying the same word bodies verbatim but a bounded self-execution
tail, comparable in scale to the campaign's other workloads. The
originals are untouched; only multiuser-doe.4th's own WL-CAPSULE/
WL-ENTRY index 1 and 5 mappings were repointed.

Verified live before relaunching a third time: the actual worst case
in isolation (5 0 998 MU-RUN-TRIAL, concurrency=8 heterogeneous,
includes both fixed workloads plus RUN-OMNI) completed in ~20 minutes
wall-clock, Hera stayed healthy throughout. Clean 3-arch qemu boot.

Reps reduced 60 -> 30/cell (Bob's call after seeing the real per-trial
cost) -- still matches the project's "rule of 3's" DoE convention
(same as ACL-RWT's own 30 reps). 6 cfgs x 30 reps = 180 trials.
