… field estimators Closes sbi-dev#1885 (vector field portion) - Remove assert_transform_to_unconstrained_supported guard from build_vector_field_estimator - Add x_dist parameter; build mcmc_transform when z_score_x is transform_to_unconstrained - Add _input_transform attribute and input_transform property to ConditionalVectorFieldEstimator base class - Update FlowMatchingEstimator.ode_fn() and .loss() to apply the transform before forward/loss computation - Update score estimators (ConditionalScore, VP, SubVP, VE) same pattern in ode_fn() and loss() - Update VectorFieldBasedPotential.__call__() to transform theta, add log|det J| correction - Update VectorFieldPosterior.sample_via_ode() and _sample_via_diffusion() to inverse-transform samples
