    Refactored JSON Schema generation for ComponentTool parameters using Pydantic’s model_json_schema, enabling expanded type support (e.g. Union, Enum, Dict, etc.).
    We also convert dataclasses to Pydantic models before calling model_json_schema to preserve docstring descriptions of the parameters in the schema.
    This means dataclasses like ChatMessage, Document, etc. now have correctly defined JSON schemas.
