Error type for the library 错误处理模块：提供统一的错误类型和结构化错误上下文。

Error Handling Module

This module provides unified error types and structured error contexts for comprehensive error handling across the ai-lib-rust library.

Overview

The error system provides:

• Unified Error Type: Single Error enum for all error conditions
• Structured Context: Rich ErrorContext for debugging information
• Actionable Hints: User-friendly suggestions for error resolution
• Error Classification: Retryable and fallbackable error marking

Error Categories

Variant	Description
Protocol	Protocol specification errors
Pipeline	Streaming pipeline errors
Configuration	Configuration and setup errors
Validation	Input validation errors
Runtime	Runtime execution errors
Transport	Network transport errors
Remote	Remote API errors (with HTTP status)

Example

use ai_lib_rust::error::{Error, ErrorContext};

// Create error with context
let error = Error::validation_with_context(
    "Invalid temperature value",
    ErrorContext::new()
        .with_field_path("request.temperature")
        .with_details("Value must be between 0.0 and 2.0")
        .with_hint("Try setting temperature to 0.7 for balanced output"),
);
