Pull request overview

This PR adjusts binned_residuals() to better support checking linearity of the logit for logistic regression by changing the default residual type from deviance to response residuals (per Gelman & Hill), and updates package metadata and tests accordingly.

Changes:

• Change binned_residuals() default residuals to "response" and update parameter documentation to justify the default.
• Update test expectations and add a new simulation-based test around the “linearity of the logit” use case.
• Record the breaking change in NEWS.md and bump the development version in DESCRIPTION.

• The Rd examples currently error: they create d <- ... but then call glm(..., data = df) where df is undefined. This should be fixed (ideally by regenerating from roxygen after updating R/binned_residuals.R).
