Added support for customizing processors in `scripts.js` (esbuild), `styles.js` (node-sass, postcss, autoprefixer), and `svgs.js` (svg-mixer), via arguments for the exported task functions.
Added:
- Constants to decouple shared default options, options for development, and options for production.
- Constants to export default options for development and production as an array of arguments to pass to task functions.
Changed:
- watch.js to apply development args to tasks
