mmbcv 1.0.0 (2026-07-22)

Added heterogeneity_test() for testing equality of transition-specific effects.
Added linear_trend_test() for testing GLS linear trends.
Added order_restricted_test() with chi-bar-square inference.
Added support for coefficient subsets and user-specified transition scores.
Created separate help pages for the three tests.
Reorganized internal testing functions into separate source files.

Added heterogeneity_test() for an omnibus Wald test of equality among selected transition-specific coefficients.
Added linear_trend_test() for one- or two-sided generalized least-squares trend tests with equally or unequally spaced transition scores.
Added order_restricted_test() for monotone increasing or decreasing alternatives using a chi-bar-square reference distribution.
All three tests accept integer, logical, or character coefficient selection through index and work with any conformable covariance estimator returned by MMBCV().
The order-restricted test calculates analytic chi-bar-square weights for one or two inequalities and simulation-based weights for higher dimensions. It returns the weights, weight Monte Carlo standard errors, and p-value Monte Carlo standard error, and accepts precomputed weights when desired.
