AIBias 0.1.1

• Updated amplification index to a mechanism-oriented sign convention: A_t = (p11_ref - p11_group) - (p01_ref - p01_group). Negative values indicate recovery-driven amplification against the focal group; positive values indicate retention-driven amplification.
• Added sign argument to aib_amplify() with options "mechanism" (default) and "legacy" for backward compatibility.
• Improved documentation to clarify sign interpretation.
• Fixed: \dontrun{} replaced with \donttest{} in examples.
• Fixed: added \value tags to print.aibias and summary.aibias.
• Fixed: aib_figures() default path now uses tempdir().

# AIBias 0.1.0

Resubmission notes

• Removed author surnames from DESCRIPTION to avoid spell check false positives (Barocas, Hardt, Narayanan, Gelbach replaced with neutral citation wording).

• Added .gitignore to exclude cran-comments.md from the repository.
