Filter files in copyToTemp using .gitignore rules

Updated the `copyToTemp` function to respect ignore patterns defined in `.gitignore` files and exclude unwanted files like `node_modules`, `dist`, and `build`. This ensures that only relevant files are copied to the temporary directory, improving efficiency and alignment with project standards.
