Add Linting / formatting rules for code uniformity.

Set up a prettierrc to enforce code style and possibly add it as a workflow / pre-commit hook to the project to help maintain be uniform.

Start by inspecting the existing project scripts and configuration to determine how formatting is currently handled. Define the requested Prettier configuration and decide whether enforcement belongs in a workflow or pre-commit hook. Done means the chosen formatting rules are applied consistently and the selected automated check runs successfully.
