feat: Support OLLAMA provider

- Added OllamaClient to handle conversations with the Ollama API.
- Introduced OllamaDialect for managing thinking modes.
- Created data classes: OllamaFunctionCall, OllamaListedModel, OllamaMessage, OllamaShowRequest, OllamaShowResponse, OllamaTagsResponse, OllamaToolCall, OllamaToolDefinition, and OllamaToolFunction for structured API communication.
- Developed unit tests for OllamaClient to validate model listing, chat completion, streaming responses, and tool calling capabilities.
- Configured test properties for local Ollama instance.
