refactor: Optimize agent component for efficiency and readability

[Arikatakur]

Overview

This PR refactors the LCAgentComponent and LCToolsAgentComponent classes to improve code efficiency, readability, and maintainability. The changes focus on reducing redundancy, optimizing data handling, improving error handling, and simplifying logic.

---

Changes Made

1. Reduced Redundancy:

   • Removed repeated hasattr checks by storing results in variables.
   • Simplified the get_agent_kwargs method to return a single dictionary.

2. Optimized Data Handling:

   • Used list comprehensions and generators to avoid unnecessary data copies.
   • Cached repeated computations like data_to_messages(self.chat_history).

3. Improved Error Handling:

   • Consolidated exception handling in the run_agent method.
   • Added logging for unexpected errors to make debugging easier.

4. Simplified Logic:

   • Removed deprecated features like agent_description.
   • Combined build_agent and create_agent_runnable logic where applicable.

5. Enhanced Readability:

   • Added docstrings to methods for better documentation.
   • Used consistent formatting and meaningful variable names.

Why These Changes?

• Efficiency: The refactored code reduces unnecessary computations and improves performance.
• Readability: The changes make the code easier to understand and maintain.

---

Impact

• Performance: The agent component should now run faster due to reduced redundancy and optimized data handling.
• Debugging: Improved error handling and logging make it easier to diagnose issues.
• Future Development: The simplified logic and improved readability make it easier to add new features or modify existing ones.
