v0.2.0

• New tab redesigned: AIsNav now loads directly inside the new tab page,
keeping the address bar blank and ready for typing.
• The extension now does one thing only — it replaces the new tab page.
Homepage and startup-page overrides have been removed.
• Reduced site access: the extension only accesses aisnav.com.
• The welcome page now follows your browser language (English / Chinese).
