Subject: [PATCH] feat: add preview version badge for nightly builds (#8222)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Summary

Adds a "Preview Version" badge to the topbar on nightly builds to help
users identify when they're using an unreleased version and encourage
feedback.

## Changes

- Add `nightly.badge` i18n translations (label and tooltip)
- Create `nightlyBadges.ts` extension with info variant badge
- Load nightly badges extension when `isNightly` is true
- Badge tooltip encourages users to provide feedback via the feedback
button

## Test plan

- [ ] Build and run nightly version, verify "NIGHTLY | Preview Version"
badge appears in topbar
- [ ] Hover over badge, verify tooltip shows: "You are using a nightly
version of ComfyUI. Please use the feedback button to share your
thoughts about these features."
- [ ] Verify stable OSS builds don't show the badge
- [ ] Verify cloud builds don't show the nightly badge
