Re-tune _LEVERED_SLEEVE_SHAPE from the Sharpe-max fixed shape (carry ~53%) to a
tail-budgeted one (carry ~40%, non-carry inverse-vol): {tstrend 1.0, unlock 2.2,
xsfunding 3.0, positioning 1.3}. Caps a -20% carry dislocation to ~-8% of the book
(vs -10.5%) while keeping Sharpe ~2.7 (>> naive 2.26). One constant re-tunes the
whole levered chain. A new invariant test pins carry at 40% of gross. 1824 pass.
