Instead of inline parsing examples in basic client code, this commit adds a dedicated 'Parsing Tool Results' section under Advanced Usage that comprehensively documents: - The structure of CallToolResult (content, structuredContent, isError) - How to parse different content types (TextContent, ImageContent, EmbeddedResource, ResourceLink) - Structured output handling for tools with outputSchema - Proper error handling using the isError field This provides a cleaner, more comprehensive reference for developers working with tool results in MCP. Github-Issue: modelcontextprotocol#812
The example in README.md for parsing the result of `session.call_tool` has been updated to reflect the structure of `CallToolResult`. This change aligns the README example with the type definitions in `mcp/types.py`.

- Add new section under Advanced Usage for parsing CallToolResult objects - Create comprehensive example showing all content types (text, structured, embedded resources, images, errors) - Move parsing documentation to a dedicated section instead of inline examples - Improve discoverability and clarity of tool result parsing patterns
The original author's inline parsing examples are now redundant since we have a dedicated 'Parsing Tool Results' section under Advanced Usage. This commit removes all the duplicated content, keeping the documentation clean and focused.

Thank you for this contribution!
I think adding some parsing examples like this to docs makes sense - but I don't think we should be modifying existing code snippets + duplicate it in multiple places.
I've instead created a new section part of Advanced Usage specifically for parsing tool results of different types as an example and pushed that to this PR.
