Remove Agents class

[heyitsaamir]

We had this experimental class called Agents that was basically a "stateful" ChatPrompt. To align with other languages, this class doesn't add much value, and is taking on additional support pressure. So I'm going to remove it in interest of just ChatPrompt.

ChatPrompt now supports "memory" so if you give it memory when you construct it, it'll use that memory instance for subsequent calls (which is basically what Agent did).

So TLDR: Change Agent to ChatPrompt in your code to migrate.

Pull Request Overview

This PR removes the experimental Agent class and consolidates its functionality into ChatPrompt by adding an optional memory parameter to the ChatPrompt constructor. This change aligns the Python SDK with other language implementations and reduces API surface area.

Key changes:

• Added optional memory parameter to ChatPrompt.__init__() to enable stateful conversations
• Modified ChatPrompt.send() to use constructor-provided memory as default when no explicit memory is passed
• Removed the entire Agent class and its module
• Updated all test applications to use ChatPrompt instead of Agent

The new memory parameter in the ChatPrompt constructor lacks test coverage. While the existing tests verify memory functionality when passed to send(), there are no tests verifying that memory set in the constructor is properly used as a default. Consider adding a test that creates a ChatPrompt with memory in the constructor and verifies it's used across multiple send() calls without explicitly passing memory each time.

@copilot can you make sure we test the case with a memory in constructor at least once?
