jgrusewski e132d59a48 feat(rl): confidence gate — override low-certainty openings to Hold ...

New rl_confidence_gate.cu kernel computes C51 distributional Lower
Confidence Bound (μ - λσ) / σ_norm for the chosen action. When
position is flat and the selected action is an opening (a0/a1/a5/a6),
overrides to Hold if conf < threshold.

Fires after π action selection, before trail/heat/market pipeline.
Only gates on flat positions — existing positions pass through
unconditionally regardless of Q uncertainty.

ISV slots: 512 threshold (0.10), 513 λ (1.0), 514 σ_norm (1.0),
           515 fired_count (diag). RL_SLOTS_END → 516.

GPU oracle test: 4 cases (low-conf gate, high-conf pass, non-flat
bypass, non-opening bypass).
