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

# TRAMA: Trend Regularity Adaptive Moving Average
> *LuxAlgo counted how often price makes new highs and new lows within a window, squared that fraction, and used it as an EMA smoothing constant. Trending markets produce frequent HH/LLs and the filter tracks fast. Ranging markets produce few, and the filter stops moving. Simple, effective, elegant.*

- Requires `period` bars of warmup before first valid output (IsHot = true).
- Validated against TA-Lib, Skender, and Tulip reference implementations where available.

Trending markets produce frequent HH/LLs and the filter tracks fast. Ranging markets produce few, and the filter stops moving. Simple, effective, elegant."
TRAMA is an adaptive EMA where the smoothing factor derives from the "trend regularity" of the lookback window, measured as the fraction of bars that produce either a new highest-high (HH) or a new lowest-low (LL). This fraction is squared to create a convex penalty: low regularity (ranging) produces near-zero smoothing (filter barely moves), while high regularity (trending) produces aggressive smoothing (filter tracks closely). Developed by LuxAlgo (TradingView, December 2020).
