Feature Request: Add Support for Custom Model Configuration

[AmoghShukla]

Feature Request

Description

It would be beneficial to add support for custom model configurations to allow users to specify their own model parameters and settings without modifying the core configuration files.

Use Case

Users who want to experiment with different model settings or use custom fine-tuned models should be able to easily switch between configurations without breaking the main setup.

Proposed Solution

Add a configuration management interface that allows users to:

• Load custom model configurations from user-defined files
• Switch between configurations at runtime
• Validate configurations before applying them

This would greatly enhance the flexibility of the BettaFish platform.
