Release version 0.7.0 - Add Mistral client support

Release v0.6.0: Comprehensive agent system and improved gemspec

Release v0.5.5

* Major refactor:
  * Core classes have been extensively refactored for improved modularity, clarity, and maintainability:
    * Adopted SOLID principles throughout the codebase.
    * Extracted interfaces for memory, tool management, and all builder components, now located in a dedicated interfaces namespace.
    * Introduced a builders folder and builder pattern for prompt, memory context, tool responses, RAG documents, and retriever context.
    * Improved dependency injection and separation of concerns, making the codebase easier to extend and test.
    * Centralized error handling and configuration validation.
    * Enhanced documentation and type signatures for all major classes.
    * The public API remains minimal and idiomatic, with extensibility via interfaces and factories.
  * Chain#ask method rewritten following Ruby best practices: now declarative, each pipeline stage is a private method, code is cleaner and easier to extend.
  * All ToolManager creation and configuration is now done via a dedicated factory: ToolManagerFactory. Old calls (ToolManager.create_default_toolset, ToolManager.from_config) have been replaced with factory methods.

Version 0.5.4: Deepseek-Coder-V2 client support

This release adds support for Deepseek-Coder-V2 models, a specialized code generation LLM.

New features:
- Deepseek-Coder-V2 client with optimized settings for code tasks
- Support for multiple model variants (latest, 16b, 236b)
- Seamless integration with existing tool ecosystem
- Enhanced CLI with proper development mode detection

The Deepseek-Coder-V2 models are particularly effective for:
- Code generation and explanation
- Algorithm implementation
- Code review and optimization
- Programming language translation
