Docs: Teams MCP integration needs end-to-end audit and refresh

[bradygaster]

Summary

The Teams MCP server documentation references files and examples that don't exist in the current codebase. Needs end-to-end verification and refresh.

Origin: Discussion #140 by @msquibb

Evidence

• Docs reference examples that don't exist on disk
• Community members have created working implementations independently (see gist by @benleane83)
• Docs may be ahead of implementation

What's Needed

1. Audit Teams MCP integration end-to-end
2. Verify or remove outdated doc examples
3. Test with actual Teams incoming webhook + MCP server
4. Update docs to reflect current reality
5. Consider linking to community implementations
