docs: add live npm stats badges and update adoption section

- Replace bare Tests-only badge line with a full row: version, weekly/
  monthly/18mo downloads, license, tests, GitHub stars
- Replace static 8M+ adoption line with curated 9.2M+ since Jan 2018,
  ~64K weekly, and a link to the live npm-stat historical chart
- All numeric badges fetch live data via shields.io on every page load
