Utilize Pydantic Model for Config Loading

[IbraAoad]

Enhancement Proposal

Current Implementation

Currently, the config loading mechanism relies on a custom class (Config) and manual parsing of a YAML file.

Suggested Enhancement

The suggestion is to explore using a Pydantic model for loading and managing the configuration. Pydantic provides static typing and validation, which can enhance code clarity, maintainability, and reduce the likelihood of runtime errors.
