  1. Fix CallToolResult handling across all SDKs 

    When a tool handler returns an MCP CallToolResult object
({ content: [...], isError?: bool }), all four SDKs were
JSON-serializing it instead of converting it to ToolResultObject.
This caused the LLM to see raw JSON instead of actual tool output.

Add detection and conversion of CallToolResult in Node.js, Python,
Go, and .NET. The .NET SDK additionally handles Microsoft.Extensions.AI
content types (TextContent, DataContent, and unknown subtypes via
AIJsonUtilities serialization).

Fixes #937

  6. Remove isCallToolResult and convertCallToolResult from public exports 

    These are internal implementation details used by session.ts and client.ts.
Go and Python already keep them private (lowercase/underscore-prefixed).
