chore: update pre-commit hooks and development dependencies

[ceberam]

Summary

This PR updates the development tooling infrastructure by modernizing pre-commit hooks, upgrading key dependencies, and cleaning up unused packages. It also updates the documentation to reflect the current tooling setup.

Changes

Pre-commit Configuration (.pre-commit-config.yaml)

• Updated ruff execution versions
• Fixed and expanded coverage: Updated file patterns to replace tests with test (bug) and add examples directories.
• Reordered hooks: Placed ruff-check before ruff-format for logical execution order and to follow Ruff guidelines.

Development Dependencies (pyproject.toml)

• Upgraded major versions:
  • MyPy: 1.6 → 2.1.0
• Removed unused dependencies (Flake8, autoflake, isort,...)

Documentation (CONTRIBUTING.md)

• Updated code style guidelines section to reflect current tooling
• Removed references to deprecated tools (Flake8, autoflake)
• Added link to Ruff documentation
• Clarified that only Ruff and MyPy are used for code quality enforcement

Code Formatting

• Applied automated code style formatting across the codebase
• Fixed docstring formatting (raw strings where needed)
• Removed unnecessary blank lines
• Ensured consistency with updated style rules

Testing

• All pre-commit hooks pass successfully
• Code formatting has been applied consistently across the project

Impact

• No breaking changes to the library API
• Development workflow remains the same for contributors
• Improved CI/CD performance with local hook execution
• Cleaner dependency tree with removal of unused packages
