docs: clarify mcp_dart positioning versus dart_mcp

[leehack]

Summary

• Add README guidance for choosing between the community mcp_dart SDK and the official dart_mcp package.
• Position mcp_dart around production-oriented Dart/Flutter MCP servers, clients, transports, auth/security, tooling, and latest protocol compatibility.
• Remind readers to re-check current pub.dev/docs before making a production decision.

Test Plan

• Not run (documentation-only README change).

Notes

• This handles the Obsidian candidate “Document positioning vs official dart_mcp” directly in the repository.
