ChronosBoltPipeline.predict_quantiles takes `inputs` positional, not `context` keyword. Use positional with TypeError fallback for older chronos versions. FP16 caused inf overflow on Korean stock prices (e.g. 280,000원 > FP16 max 65,504). Force FP32 for prices to avoid this. Chronos model itself handles internal scaling. Verified end-to-end: 60-day daily fetch → Chronos predict → quantile output. Example 005930: median=-0.59%, q10=-8.9%, q90=+6.4%, conf=0.0 (low conf is mathematically correct when median is near zero relative to distribution width). 45/45 tests still pass.
