Add llm_balanced.push3: arithmetic-only optimizer that keeps all
outputs in a balanced mid-range. anchorShare=40-60% (linear with
percentageStaked), anchorWidth=10-200 ticks (linear with taxRate),
discoveryDepth=30-50% (linear with percentageStaked), ci=0. No
EXEC.IF branches — all transitions via multiplication and division.
