Feature: Add Favicon

[ShinichiShi]

Hey @Riddhi050803, I have added the favicon making sure it matches the theme. Here is the before/after image 👇

• Fixes: #13
• the favicon being purple kind of symbolized unity and calm balance, aligning with the zen meditation theme
• Kindly suggest if any changes
