Summary: ChatGPT adds "Sign up for free" and new tool shortcuts.

Why It Matters: The site is now pushing harder for new user sign-ups and showing off specific things the AI can do, like making images or using voice.

What Changed:

• Added a "Sign up for free" button to the main view.
• Added "Create image" and "Voice" as quick action buttons.
• Removed the prominent "Temporary Chat" privacy notice from the landing view.
