Enhanced Error Handling, Code Updates, and Implementation of Tree of Thoughts Method

[brucemeek]

Hello @rihp,

I've been working on your AutoGPT Planner Plugin and made some modifications that I believe could enhance its functionality and robustness. Here's a summary of the changes:

Enhanced Error Handling: I've added more robust error handling to ensure the plugin can recover gracefully from unexpected situations.

Code Updates: I've made some updates to the code to improve its readability and maintainability.

Implementation of Tree of Thoughts Method: I've implemented the Tree of Thoughts method, which allows for more structured and efficient planning. This new feature enhances the plugin's ability to create and manage tasks.

Additional Configurations: I've added more configuration options to allow users to customize the plugin's behavior to better suit their needs.

Testing Workflow: I've updated the testing workflow to make it easier for other developers to test their changes.

You can review the changes in my forked repository here.

I believe these changes could significantly improve the plugin's performance and user experience. I'd appreciate it if you could review my changes and consider merging them into the main repository.

Best, Bruce
