feat: add RRSI (Rocket RSI) — Ehlers TASC May 2018

Algorithm: SuperSmoother-filtered momentum → Ehlers RSI → Fisher Transform - 2-pole Butterworth IIR pre-filter removes noise - Ehlers RSI (raw summation, not Wilder) outputs [-1,1] - arctanh produces Gaussian-distributed zero-mean oscillator Files: Rrsi.cs, Rrsi.Quantower.cs, Rrsi.md, 31+7 tests Integration: sidebar, indices, Python bridge (Exports, _bridge, oscillators, SPEC) Build: 0 warnings, 0 errors | Tests: 15,963 passed, 0 failed
