 ### 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.

+Add a feature to the Make file that updates the updates.json file based on available signed releases.
+
+### Assistant outcome
+Added `make update-updates`, which regenerates `webextension/updates.json` from valid versioned signed XPIs. The generator reads each packaged manifest, validates its version, add-on ID, and Firefox minimum version, and ignores non-release artifacts.

+### User
+Add sha hashes to the updates.json
+
+### Assistant outcome
+Added Firefox-compatible `sha256:<hex>` update hashes generated from each signed XPI's bytes. Release validation now rejects missing or mismatched hashes; the generated metadata and release validator passed for signed versions 0.2.0 and 0.1.0.

+
+### Assistant outcome
+Recorded the signed-XPI update metadata automation and SHA-256 integrity hashes in the v0.2.0 changelog and VIBE logs.

+
+### Assistant outcome
+Extended `make update-updates` to set the About page plugin download URL to the newest valid signed XPI. Release validation now also rejects an About page whose link does not match the latest signed artifact; verified with LinkLog 0.2.0.
