* Add Prettier configuration and ignore files for code formatting - Created .prettierignore to exclude specific directories and files from formatting. - Added .prettierrc.yml with custom settings for print width and trailing commas. - Updated package.json to include Prettier and its Solidity plugin as dependencies, along with scripts for formatting and checking code. * Run prettier formatting
