chore: enhance clangd and CI configurations for improved development experience

- Updated `.clangd` configuration to include additional include paths and feature flags tailored for ROM hacking workflows, optimizing IntelliSense support.
- Introduced `.pre-commit-config.yaml` for managing code quality checks and formatting, ensuring consistent code style across the project.
- Added `cmake-format.yaml` for CMake formatting configuration, promoting adherence to style guidelines.
- Enhanced CI workflows to include new actions for testing and building, improving overall reliability and efficiency in the development process.

Benefits:
- Streamlines development setup and improves code quality through automated checks.
- Facilitates better collaboration by ensuring consistent coding standards and configurations.
