Minor Changes

• #3708 3d4a76f Thanks @pauldambra! - Detect Brave (desktop, Android, iOS), Vivaldi, Yandex, Naver Whale, DuckDuckGo, Pale Moon, and Waterfox so users on these browsers no longer get bucketed as Chrome or Firefox.

  detectBrowser / detectBrowserVersion now accept an optional third argument, BrowserDetectionHints, with a brave flag (set when navigator.brave exists). The browser SDK populates this automatically to catch desktop / Android Brave, which is Chromium-based and carries no UA marker. Brave on iOS is picked up purely from the Brave/ UA marker — WebKit doesn't ship navigator.brave. The original two-argument signature still works for non-DOM callers. (2026-06-01)
