/**
* An error that can be thrown from a tool's `run` method to return structured
* content blocks as the error result, rather than just a string message.
*
* When the ToolRunner catches this error, it will use the `content` property
* as the tool result with `is_error: true`.
*
* @example
* ```ts
* const tool = {
* name: 'my_tool',
* run: async (input) => {
* if (somethingWentWrong) {
* throw new ToolError([
* { type: 'text', text: 'Error details here' },
* { type: 'image', source: { type: 'base64', data: '...', media_type: 'image/png' } },
* ]);
* }
* return 'success';
* },
* };
* ```
