Release v0.1.1: hide sponsored listings, broaden detail-page detection

- Hide any card whose anchor carries `journey=FEATURED_LISTING_JOURNEY`
  or whose container is tagged featured/sponsor/promoted.
- Detail-page URL regex now also matches `/classifieds/advert/{id}` and
  `/cars/{slug}/{id}` in case AutoTrader redirects through either.
- Added a `[ATM]` console.log at init so unresolved detection issues can
  be diagnosed from Firefox DevTools.
