Linting is not properly working

### Steps To Reproduce

Linting is not properly working, was introduced in #45. It also appears be trying to lint the files in the 'dist' folder.

### Expected Result

Only lint Typescript files, not the files/bundles generated by rollup.

### Actual Result

`npm run format` lints all files with `*.js` and `*.vue` extensions.

### Screenshots or Videos

n/a

Start with the configuration and command behind `npm run format`, then trace why its file patterns include JavaScript and Vue files under `dist`. Done means formatting lints only TypeScript source files and excludes Rollup-generated bundles in `dist`.
