gahusb 28f9c8c3a6 feat(signal_v2-phase3b): chronos_predictor + 4 mock tests ...

ChronosPredictor wraps HuggingFace ChronosPipeline. Batch predict
returns ChronosPrediction(median, q10, q90, conf, as_of) per ticker.
Confidence = 1 - clamp(spread/2, 0, 1) where spread = (q90-q10) / |median|.
Lazy import of chronos lib (heavy). GPU auto-detect with FP16.

44 tests pass.
