docs: add rudof-mcp to the "Built with rmcp" list in the README

[samuel-bustamante]

Motivation and Context

rudof-mcp is a production-ready MCP server built with rmcp that showcases several advanced features of the SDK. Adding it to the list provides another reference implementation for developers looking to build MCP servers with rmcp, particularly those interested in:

• Dual transport support (stdio + streamable HTTP)
• Full MCP capabilities implementation (tools, prompts, resources, logging, completions)
• Docker MCP Registry integration with state persistence

How Has This Been Tested?

None. This is a documentation-only change.

Breaking Changes

None. This is a documentation-only change.

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change)
• Documentation update

Checklist

• I have read the MCP Documentation
• My code follows the repository's style guidelines
• New and existing tests pass locally
• I have added appropriate error handling
• I have added or updated documentation as needed

Additional context

rudof is an RDF, ShEx, and SHACL processing library. The MCP server exposes its functionality to AI assistants, enabling them to load, validate, query, and transform RDF data. The implementation can serve as a reference for building complex MCP servers.
