jgrusewski 7753cbef1b feat(sp15-p3.3): quadratic DD penalty + ISV-driven λ + threshold
Per spec §8.2 (3.3). penalty = λ_dd × max(0, dd_current − dd_threshold)²

Asymmetric: zero below threshold, quadratic growth above. Encodes loss
aversion per pearl_audit_unboundedness_for_implicit_asymmetry.

3 ISV slots: 420 LAMBDA_DD (initial 1.0; ISV-tracked from grad-balance
in follow-up), 421 DD_THRESHOLD (initial 0.05 = 5% drawdown trigger),
422 DD_PENALTY_GRAD_NORM (initial 0.0).

3 fold-reset registry entries + dispatch arms.

Per established Phase precedent: kernel + launcher land first; reward
composition site (subtract penalty from r_total) deferred to follow-up
commit per feedback_no_partial_refactor.

Anchor test 2.5 drawdown_de_risks (Phase 2C / Phase 3.5 paired) — green
via Phase 3.5 mechanisms; this commit lands the penalty primitive.
