//! Model Context Protocol (MCP) client implementation.
//!
//! ## Modules
//!
//! - [`core`]: MCP client infrastructure (manager, config, connections)
//! - [`inventory`]: Tool storage and indexing
//! - [`approval`]: Approval system for tool execution
//!
//! ## Shared Types
//!
//! - [`ToolAnnotations`]: Tool behavior hints (read_only, destructive, etc.)
//! - [`TenantContext`]: Per-tenant isolation and configuration

// Shared types (used across modules)

// Subsystems
