feat(oscillators): add DSO - Ehlers Deviation-Scaled Oscillator
...
Implement DSO (TASC Oct 2018) with SSF 2-pole filter, RMS normalization,
and Fisher Transform (±0.99 clamp). Sealed class, O(1) streaming RMS via
RingBuffer, precomputed SSF coefficients.
New files: Dso.cs, Dso.Quantower.cs, Dso.md, dso.pine,
Dso.Tests.cs (27), Dso.Validation.Tests.cs (7), Dso.Quantower.Tests.cs (11)
Updated: Exports.cs, _bridge.py, oscillators.py, SPEC.md,
_sidebar.md, lib/_index.md, oscillators/_index.md,
docs/indicators.md, docs/pinescript.md
All 19,565 tests pass, 0 warnings.

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

feat: add 8 new indicators with full integration
...
New indicators:
- HWC (Holt-Winters Channel) — channels, 27 tests
- VWMACD (Volume-Weighted MACD) — momentum, 38 tests
- Squeeze Pro — oscillators, 69 tests
- BW_MFI (Bill Williams MFI) — oscillators
- DSTOCH (Double Stochastic) — oscillators
- ATRSTOP (ATR Trailing Stop) — reversals
- VSTOP (Volatility Stop) — reversals
- Convexity (Beta Convexity) — statistics, 23 tests
Integration:
- Python bridge: Exports.cs, _bridge.py, wrapper modules
- Documentation: _sidebar.md, _index.md pages, SPEC.md
- All analyzer warnings fixed (MA0074, xUnit2013, S2699)
Build: 0 warnings, 0 errors | Tests: 15,933 passed, 0 failed
