Add B10 Ehlers / Cycle deepening (10 indicators) (#199)
Deepens the **Ehlers / Cycle (DSP)** family (B10) with ten indicators (452 -> 462): - **HighpassFilter**, **Reflex**, **Trendflex**, **CorrelationTrendIndicator**, **AdaptiveRsi**, **UniversalOscillator** — scalar (f64) Ehlers filters/oscillators. - **AdaptiveCci** — efficiency-ratio-adaptive CCI on typical price (Candle input). - **BandpassFilter**, **EvenBetterSinewave**, **AutocorrelationPeriodogram** — multi-arg scalar (hand-written bindings; the wasm variadic scalar macro covers wasm). Verified locally: 3755 core lib + 420 doc tests, clippy clean, 537 node tests, 881 pytest, counter 462.
