This pull request introduces several improvements focused on code quality enforcement, modernization, and consistency across the codebase and documentation. The key changes include adding a new code quality workflow for CI, enforcing linting and type-checking with pre-commit hooks, updating documentation to reflect these tools and workflows, and modernizing code style for clarity and consistency.

Code Quality and CI Integration:

• Added a new GitHub Actions workflow (.github/workflows/code-quality.yml) to run linting, formatting, and type-checking (Ruff and mypy) on all pushes to master/dev and all pull requests.
• Introduced a .pre-commit-config.yaml to enforce Ruff linting/formatting and mypy type-checking on all Python files, including notebooks and scripts, with pinned tool versions for reproducibility.

Documentation Updates:

• Expanded CONTRIBUTING.md with a new "Code quality" section explaining how to install, configure, and use the linting and type-checking tools, as well as CI expectations and tool versioning.
• Updated code examples in documentation and guides to use consistent, modern Python formatting (e.g., double quotes, dictionary formatting, and variable naming). [1] [2] [3] [4] [5] [6] [7] [8] [9]

Dependency and Environment Management:

• Added a temporary Python version ceiling (python<3.15) to multiple environment.yml files to avoid incompatibility with pyarrow on Python 3.15. [1] [2]
• Updated gp-elite dependency version in algorithms/gp-elite/requirements.txt to >=0.8.0.

Code Modernization and Cleanup:

• Refactored algorithms/tir/regressor.py and experiment/assess_symbolic_model.py for improved code style, clarity, and consistency (e.g., dictionary formatting, string quoting, argument parsing). [1] [2]
• Minor update to experiment/conftest.py for formatting consistency.
