Make stats table more compact and informative

- Reduced column widths to minimum needed
- Category column sized to fit longest category name (16 chars)
- Added all requested categories:
  - JavaScript, TypeScript
  - React Components (when detected)
  - Stylesheets
  - CommonJS Modules, ECMA Modules
  - node_modules (separate from source)
  - Your Code (excluding node_modules)
  - Tests
  - All Code (grand total)
- All counts properly exclude node_modules except for node_modules and All Code rows
- Added high coupling warning when imports/file > 10
