Summary of Changes

Hello @holtskinner, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly streamlines the project's Python development environment by migrating all tool-specific configurations into a single, central pyproject.toml file. This consolidation simplifies project setup, improves maintainability, and provides a unified source of truth for how various Python tools should behave within the project.

Highlights

• Centralized Configuration: All Python tool configurations for coverage, mypy, and ruff have been consolidated into the pyproject.toml file, reducing the number of separate configuration files.
• File Removal: The individual configuration files .coveragerc, .mypy.ini, and .ruff.toml have been removed from the repository.
• pyproject.toml Enhancements: The pyproject.toml file now includes comprehensive settings for coverage, mypy, and ruff, mirroring the configurations previously held in their dedicated files. Additionally, build system configurations for hatchling and uv-dynamic-versioning were adjusted, and an exclusion for tests/ was added to the sdist target.

Code Review

This pull request is a great step towards modernizing the project's configuration by consolidating settings into pyproject.toml. The migration of .coveragerc, .mypy.ini, and .ruff.toml is mostly correct. I've found a critical issue with a duplicated table in the Ruff configuration that would break the TOML parsing, and a minor omission of a rule from the ignore list. Once these are addressed, this will be a solid improvement.
