Add formatting and static analysis scripts with usage instructions

- Introduced new scripts for auto-fixing formatting and performing static analysis across the project, including support for Lua, Rust, and TypeScript.
- Created `format.md` documentation to guide users on running the formatting scripts.
- Updated CI scripts to utilize the number of processor threads for improved performance during linting and testing.
- Enhanced logging in the `unwatch` function to provide clearer feedback on path watching status.

These changes streamline the formatting and analysis process, ensuring consistent code quality across the project.
