What's new in 2.5.1:
- Auto update-check: the popup now checks GitHub every few days for a new version. If one exists, a green banner appears with a direct Download button. Dismissable per-version — stays quiet until an even newer release.
- Add a Post: clearer hint inviting users to add bookmarks and posts worth preserving.
- Zero new permissions: the update check uses the CSP connect-src allowlist (api.github.com added). No new chrome.permissions, no new host_permissions. Privacy surface unchanged.
How to install/update: see the README.
