Refactor PromptClientInput to accept string array for prompt (#336)

* Refactor PromptClientInput to accept string array for prompt

Updated the `PromptClientInput` method to accept a string array instead of a single string. This change ensures that multiple prompts can be handled, improving input flexibility and client communication. Additionally, modified related method calls to maintain consistency with the new input type.

* Refactor PromptClientInput to support parsed result and errors

Updated PromptClientInput to handle parsed input results and return error messages instead of raw strings. Introduced ParsedInputResult<TResult> class to encapsulate parsing results and errors, enhancing client validation and feedback mechanism.
