Summary: Superwhisper adds Windows support and navigation

Why It Matters: The product is expanding from a Mac-only tool to a cross-platform solution. This allows them to reach a much larger group of professional users who work on Windows.

What Changed:

• Added a "Download for Windows" button alongside the Mac version.
• Added a top navigation bar with links to Home, Docs, Pricing, and Download.
• Updated the hero section with a new demo video and visual layout.
• Added a specific "Download for iPhone" link in the header area.
