YieldLag 0.3.0: calibration and uncertainty

YieldLag 0.3.0 adds separate chronological interval calibration and paired year-block uncertainty estimates for regional crop-yield modelling.

Package changes

• calibration_years reserves a block after tuning and before evaluation; zero preserves the previous behavior.
• compare_crop_errors() compares paired RMSE while retaining all regions in sampled consecutive year blocks and preserving the caller's random state.
• Stress-basis and regional-effect controls support controlled ablations.
• Reports document the calibration phase, and constant-response correlations are handled without numerical warnings.
