+### Assistant outcome
+Brought `webextension/popup.js` to parity with `new-entry.js`: the duplicate check now distinguishes an exact title/URL match from a title match with a differing stored URL (using the same `/api/links/check` `url_matches`/`stored_url` fields) and shows an additional localized note in the latter case; added a "Re-fetch title" button that calls the backend `/api/scrape` endpoint (guarded by existing backend-permission checks) and auto-fills the title on URL blur when empty; reworked `setStatus` to render real `<br>` line breaks via DOM APIs instead of `textContent`. Added `duplicateLinkDifferentUrl`, `refetchTitle`, and `titleFetchFailed` strings to all five locale files, updated `popup.html` with the new button, and bumped `manifest.json` to version `0.2.0`. Full backend test suite (36 tests) passed.

 240. I want this last change to be more precise: I do not want to be warned when parameters are stripped, but when the URL entered has arguments/parameters and the URL in the database has none or different ones (even after tracking parameters are stripped).
 241. In the check duplicate I have a `<br>` tag, but that shows as formatted text on the page, I want a real break to occur at that position.
