//! Unified error type for the machi framework.
//!
//! This module provides the top-level [`Error`] enum that aggregates all
//! domain-specific errors from submodules. Each submodule owns its own
//! error type (e.g., [`LlmError`], [`ToolError`], [`AgentError`]), and
//! this module re-exports them for convenience.

// Re-export submodule error types for backward compatibility.
