User Story 3: Static Response

[abhizig2024]

As a user, I want the server to respond with a static message so that I receive feedback for any request.

Tasks:

Write a function to construct a simple HTTP response:
Include HTTP/1.1 200 OK status.
Add headers (e.g., Content-Type: text/plain).
Include a static body (e.g., "Welcome to ZigCat!").
Integrate the response function with the request-handling logic.
Test with curl or Postman to verify the server responds with the static message.
