AI Summary: The task is to configure the linting and formatting tools (eslint and prettier) for the jco project to work together seamlessly, preventing conflicting code formatting when running both `npm run lint:fix` and `npm run fmt`. This likely involves configuring either tool to respect the other's formatting rules or using a single tool for both linting and formatting.

AI Summary: Implement a generic progress reporting mechanism within the `jco-transpile` package of the `jco` project. This involves adding an `onProgress` callback to relevant functions (`opt.js` and `transpile.js`) to provide feedback to the user during long-running operations, similar to the previous spinner implementation. The goal is to improve the user experience during the transpilation process.
