- Create MigrationRegistry for registering and managing migration steps.
- Develop SchemaVersionResolver to determine the current database schema version.
- Add SQLiteSchemaInspector for inspecting SQLite database structures.
- Implement progress reporting tools using rich for visualizing migration progress.
- Introduce SQLiteUserVersionStore for managing schema version storage in SQLite.
- Introduced MCPHostCallbacks for optional host capabilities like sampling and logging.
- Implemented MCPHostLLMBridge to handle MCP Sampling requests and bridge to LLM service.
- Created models for structured data conversion between MCP SDK and internal data models, including tool content items, prompts, and resources.
- Enhanced error handling and logging for better traceability during sampling operations.
- Added a new `tooling` module to define a unified model for tool declarations, invocations, and execution results, facilitating compatibility between plugins, legacy actions, and MCP tools.
- Implemented `ToolProvider` interface for various tool providers including built-in tools, MCP tools, and plugin runtime tools.
