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

Browse Source 
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

> "Ease of Movement reveals when price advances effortlessly versus when it struggles against resistance. It's the market's accelerometer." — Richard W. Arms Jr.
Ease of Movement (EOM) quantifies how easily price moves relative to volume. High positive values indicate price is advancing with little resistance (low volume relative to price range), while high negative values reveal price declining easily. Values near zero suggest price is meeting resistance, requiring substantial volume to produce movement.
The elegance of EOM lies in its normalization: it divides price change by a "box ratio" that accounts for both volume and price range. This makes the indicator comparable across securities with different price and volume characteristics.
