Summary by CodeRabbit

• Improvements
  • Saving a personal access token refreshes the GitHub rate-limit information shown in the app. Removing the token also clears the cached rate-limit information.
  • Rate-limit information stays consistent with the latest token change, even if an earlier request finishes afterward.
  • The save button shows “Saved” when a nonempty draft matches the saved token and updates as the draft changes.

Walkthrough

Saving a PAT now fetches rate-limit data and updates rate-limit state when the latest save request returns a result. Clearing a PAT removes its stored token and rate limit. The Settings page and PAT modal derive their saved labels from the saved token and trimmed draft.

Changes

PAT save flow

Layer / File(s)	Summary
PAT storage and rate-limit update src/context/AppContext.jsx	savePat assigns request IDs to save and delete operations. It stores a provided token and fetches the rate limit. Only the latest request can update rate-limit state and storage, and only when a rate limit is returned. Clearing a token removes the stored token and rate limit and clears rate-limit state.
Saved-state indicators src/pages/SettingsPage.jsx, src/components/PATModal.jsx	Both save controls derive their “Saved” label from a nonempty saved token that matches the trimmed draft. The temporary saved state and reset timers are removed. Other changes reformat existing code.

A PAT save can trigger a misleading quota-refresh error while its own quota request is running. This is a bounded UI issue; follow up on distinguishing invalidation from fetch failure.

_{I’m a rabbit watching tokens glow,
A rate-limit fetch begins to flow.
The saved draft stays in view,
The newest request updates too.
I nibble clover, then hop away.}
