strategyr 0.1.3.5

• Updated asset-year strategy mining to compute strategy signals on a warmup window before each evaluation year, then backtest only the trade-year slice.
• Added warmup metadata to asset-year mining results so signal and evaluation windows are reproducible.
• Updated real-data mining examples to show warmup-aware asset-year results.

strategyr 0.1.3.4

• Added an asset-year strategy-mining helper that seeds candidate parameter rows from selected assets, evaluates valid asset-year pairs, filters for strategy total return above buy-and-hold, and ranks survivors by Sortino.

strategyr 0.1.3.3

• Fixed calc_ADX() smoothing so ADX directional indicators match TTR::ADX() on the shared non-NA region.

strategyr 0.1.3.1

• Fixed native backtest recorder handling so rec = FALSE no longer forms a reference from a null recorder pointer.
