/**
 * Example of how to use the chat components with Vercel AI SDK v5
 *
 * This example shows how to:
 * 1. Use UIMessage directly from the AI SDK
 * 2. Handle different part types in messages
 * 3. Create custom tools and data parts

/**
 * Key points about the simplified approach:
 *
 * 1. **Use UIMessage directly**: No need for custom EnhancedMessage types
 *
 * 2. **Leverage parts system**: Different content types are handled through message.parts
 *    - 'text' parts for regular text content
 *    - 'file' parts for file attachments
 *    - 'tool-{toolName}' parts for tool invocations (following AI SDK v5 pattern)
 *    - 'data-{dataType}' parts for custom UI components
 *
 * 3. **Tool parts follow AI SDK v5 pattern**:
 *    - type: 'tool-{toolName}'
 *    - state: 'input-available' | 'output-available' | 'output-error'
 *    - args: input parameters
 *    - output: tool execution results
 *
 * 4. **Custom data parts for UI components**:
 *    - type: 'data-{dataType}' (e.g., 'data-reference', 'data-menu')
 *    - Contains the data needed to render custom UI components
 *
 * 5. **Helper functions available**:
 *    - getTextContent(message): Extract all text from message parts
 *    - hasToolPart(message, toolName): Check if message has specific tool
 *    - getToolPart(message, toolName): Get specific tool part
 *    - hasFilePart(message): Check if message has file attachments
 *    - getFileParts(message): Get all file parts
 *    - hasDataPart(message, dataType): Check for custom data parts
 *    - getDataPart(message, dataType): Get specific data part
