Fix: Replace AIML with Gen-AI chatbot integration

[Avijain15]

Summary

Refactors the chatbot in Speak Activity to use Gen-AI for more natural conversations.

Motivation

The AIML-based chatbot was limited. Gen-AI enables dynamic, context-aware responses and improves user experience.

Key Changes

• Removed AIML kernel and integrated OpenAI GPT-3.5-turbo API
• Added new ai_services.py for modular Gen-AI logic
• Updated requirements and documentation
• Improved error handling for API connectivity

How to Test

1. Set OPENAI_API_KEY in your environment.
2. Launch Speak Activity and interact with the chatbot.
3. Check for graceful error messages if the API key is missing or invalid.

Feedback Requested

• Are there edge cases in the chatbot flow I might have missed?
• Suggestions for improving error handling or user messaging?

Thanks for taking the time to review this PR!

What is the reason in changing the license agreement statements at the start of the code

[amannaik247]

from gettext import gettext as _

from gi.repository import Gdk
from gi.repository import GLib
from gi.repository import Gio

from sugar3 import profile

from aiml.Kernel import Kernel
import voice

You have removed all the existing imports?
How do you think you will get profile information from about the user?

I removed those imports inorder to reduce the complexcity of the code because shifting to a API based approach allow us to leverage the external services. I hope this resolves your issue.If not please let me know

• the activity must continue to work without internet,
• do not add copyright statements by any other person other than yourself,
• do not change license for a copyright by others,
• use a separate source file in order to add functionality under a new copyright and license,
• provide any API key with the application source code; it is not possible to distribute the application without an API key, because then it would not work,
• use our guidance for writing commit messages, see sugar-docs contributing.
