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

-Initialize:
-  highBuf = RingBuffer(senkouBPeriod)  // covers all windows
-  lowBuf = RingBuffer(senkouBPeriod)
-  bar_count = 0
-
-On each bar (high, low, close, isNew):
-  if !isNew: restore previous state (including buffer snapshots)
-
-  highBuf.Add(high)
-  lowBuf.Add(low)
-  bar_count++

-  // Tenkan-sen (shortest window)
-  tenkan = (Max(highBuf, tenkanPeriod) + Min(lowBuf, tenkanPeriod)) / 2

-  // Kijun-sen (medium window)
-  kijun = (Max(highBuf, kijunPeriod) + Min(lowBuf, kijunPeriod)) / 2
-
-  // Senkou Span A (computed now, plotted displacement bars forward)
-  senkouA = (tenkan + kijun) / 2

-  // Senkou Span B (longest window, plotted displacement bars forward)

-  // Chikou Span (current close, plotted displacement bars backward)
-  chikou = close

-  output:

-    Kijun   = kijun          // plot at current bar
-    SenkouA = senkouA        // plot at bar + displacement
-    SenkouB = senkouB        // plot at bar + displacement
