Added a language picker in the side panel: choose any of the 36 supported interface languages, or keep Auto to follow your browser language. The choice also applies to the language of check results.

Firefox fixes and reliability work:

• Clicking a timecode in the side panel now seeks the video correctly on Firefox.
• The toolbar button now opens and closes the sidebar on Firefox. Previously there was no toolbar button at all, so the sign-in screen was only reachable through the View menu.
• "Try again" after a failed check now works even if the background worker was unloaded in the meantime; when the original selection can no longer be recovered, the card says so instead of silently doing nothing.
• The side panel no longer closes or sticks when several browser windows are open.
• A check that takes too long now shows a clear timeout message.
• Predictions are no longer counted as disputed claims in the summary.

Localized interface: the context menu and check results now follow your
browser language — English, Russian, Chinese, French and Hindi.

Predictions are now separated from facts. Claims about the future are
listed in their own "Predictions" section instead of being reported as
unverifiable, and they no longer drag the credibility score down.

Fairer scoring when a few disputed claims sit among many verified ones —
the score now reflects the actual share of what checked out.

Removed an unused button from the YouTube player corner.

What's new in 0.1.3:

• Removed the non-functional "T" button from the corner of the YouTube player. The verdict pill in the action row is unchanged.
• The side panel no longer follows you across tabs. It stays enabled on YouTube and on tabs where you opened it yourself, instead of on every tab.
• Fixed the context menu item and the YouTube button showing Russian text regardless of browser language. The extension is now fully localised in English, Russian, Chinese, French and Hindi.
• Fixed a race that could make the first click on the toolbar icon do nothing.
