GitHub Starred At

About

## When did I star this?
Hover the Star button on any GitHub repository page and a small, quiet tooltip appears with the exact moment you starred it. Open your `/?tab=stars` list and each repository grows a discreet "Starred at" badge next to its last-updated timestamp. No more scrolling through your entire stars list to remember which of those "useful" repos from 2019 you should actually revisit.

## Features
 - **Hover tooltip on the Star button** — shows the starred date as relative time ("2 years ago"), absolute date ("Jun 26, 2024"), or both. Configurable per user.
 - **"Starred at" badge on your stars list** — added to each card on `github.com/?tab=stars`, right next to the existing "Updated" label.
 - **Local-first cache** — your starred list is synced once and cached in `chrome.storage.local`. Tooltips and badges are instant; GitHub's API is not hit on every page view.
 - **Configurable auto-sync** — refreshes in the background on an interval you control (default every 12 hours, range 1–168 hours).
 - **Manual sync button** — one-click refresh from the toolbar popup.
 - **Reacts to client-side navigation** — moving between repositories without a full page reload still updates the tooltip.
