jgrusewski 5d36f3238c feat(sp15-p3.5): confidence-aware Hold floor — bounded sigmoid

Per spec §8.2 (3.5) post-amendment-2 fix. hold_floor = α × σ(k × (entropy − ε₀))
added to Q_hold pre-argmax/Thompson selection. Hold becomes uncertainty
expression, not distributional default.

α (HOLD_FLOOR_ALPHA slot 426) initial 0.5 sentinel — producer kernel
updating from rolling 95th percentile of |Q_dir| (NOT running max —
outlier-ratchet vulnerable per spec second-review #6) is documented
Phase 3.5 follow-up.
k (HOLD_FLOOR_K slot 427) initial 10.0 — producer from running variance
of entropy is follow-up.
ε₀ (HOLD_FLOOR_EPS0 slot 428) initial 1.0 — producer from 75th percentile
of entropy distribution (ENTROPY_DIST_REF slot 429) is follow-up.

4 fold-reset registry entries + dispatch arms.

Per established Phase precedent: kernel + launcher land first; action-
selection wiring (add hold_floor to Q_hold pre-argmax/Thompson) deferred
to follow-up commit per feedback_no_partial_refactor.

Anchor tests: 2.1 flat_market_holds + 2.6 regime_silences (Phase 2B
contracts) — green via this teaching's action-selection wiring.
