Introduce the foundation for the Multi-Client Provider (MCP) architecture.
This phase includes:
- A new `McpClient` trait to abstract tool execution.
- A `LocalMcpClient` that executes tools in-process for backward compatibility ("legacy mode").
- A placeholder `RemoteMcpClient` for future development.
- An `McpMode` enum in the configuration (`mcp.mode`) to toggle between `legacy` and `enabled` modes, defaulting to `legacy`.
- Refactoring of `SessionController` to use the `McpClient` abstraction, decoupling it from the tool registry.
This lays the groundwork for routing tool calls to a remote MCP server in subsequent phases.
Adds consent management for tool execution, input validation, sandboxed process execution, and MCP server integration. Updates session management to support tool use, conversation persistence, and streaming responses.
Major additions:
- Database migrations for conversations and secure storage
- Encryption and credential management infrastructure
- Extensible tool system with code execution and web search
- Consent management and validation systems
- Sandboxed process execution
- MCP server integration
Infrastructure changes:
- Module registration and workspace dependencies
- ToolCall type and tool-related Message methods
- Privacy, security, and tool configuration structures
- Database-backed conversation persistence
- Tool call tracking in conversations
Provider and UI updates:
- Ollama provider updates for tool support and new Role types
- TUI chat and code app updates for async initialization
- CLI updates for new SessionController API
- Configuration documentation updates
- CHANGELOG updates
