Summary: LaunchDay adds public chat logs and deal stats

Why It Matters: The site now shows exactly how many people unlocked specific deals and displays the full conversation history between makers and users. This provides clear data on which types of products and offers are getting the most attention.

What Changed:

• Added a "Submit my product" button to the main navigation.
• Displayed specific "applaud" counts for every featured product.
• Added a "Number of users who unlocked this deal" metric for each product.
• Published a full, time-stamped chat log showing user interactions and feedback.
• Included a "Next LaunchDay" section with a TBD status.
• Added a "Sign in" option for returning users.
