feat(dynamics): add PlusDI, MinusDI, PlusDM, MinusDM indicators

Complete thin Dx-composition wrapper indicators with full test coverage:

- PlusDi/MinusDi: Directional Indicator wrappers (DiPlus/DiMinus from Dx)
- PlusDm/MinusDm: Directional Movement wrappers (DmPlus/DmMinus from Dx)
- Individual validation tests per indicator directory (TALib, Skender, bounds)
- Combined unit tests (DiDm.Tests.cs) and validation tests (DiDm.Validation.Tests.cs)
- Quantower wrappers + tests for all 4 indicators
- PineScript v6 implementations with compensated RMA
- Normalized .md documentation for all indicators and categories
- 182 tests passing, 0 failures

 Jurik Volatility (JVOLTY) is the adaptive volatility component extracted from Mark Jurik's JMA algorithm. Unlike traditional volatility measures that treat all price movements equally, JVOLTY uses a 128-bar trimmed mean distribution to compute a robust volatility reference that rejects outliers by design. The result: a volatility measure that remains stable during flash crashes, earnings surprises, and 5-sigma events while still tracking genuine regime changes.
