Fixes prompty pattern matching. Closes #1325

Pull Request Overview

This PR fixes prompty pattern matching by generalizing message conversions from arrays to IEnumerable<ChatMessage> and updating the empty‐check logic.

• Updated ConvertMessages signature in OpenAI and Ollama clients to accept IEnumerable<ChatMessage> instead of ChatMessage[].
• Updated the abstract ConvertMessages method in BaseLanguageModelClient accordingly.
• Changed the prompty.Empty check from array‐based (Length == 0) to LINQ’s .Any() on IEnumerable.

• There’s no existing test covering the case when prompty.Prepare(parameters) returns an empty IEnumerable. Adding unit tests for both empty and non-empty prompt scenarios would ensure this change behaves as expected.
