Add mastyf.ai to community projects

[mastyf-ai]

Add mastyf.ai to the Other section of community projects. It is a runtime MCP proxy with multi-agent policy enforcement, prompt injection detection, secret scanning, and full audit trail (published on npm as @mastyf_ai/server).

Friendly ping — this PR adds mastyf.ai to the community projects list. It's an open-source MCP security proxy, live on the Official MCP Registry as io.github.mastyf-ai/mastyf.ai and published as @mastyf_ai/server (v4.1.12). Would appreciate a review. 🙏

Thanks for the contribution, and for following the one-line format! 🙏

I took a look and, unfortunately, this list is scoped specifically to projects related to the MCP Registry — things that browse, implement, publish to, aggregate, or otherwise build on the registry itself (see the intro line and the existing sections).

mastyf.ai looks like a genuinely useful MCP runtime proxy / security gateway, but it doesn't interact with the registry, so it falls outside the scope of this particular list. Going to close this one on that basis — please don't read it as a knock on the project. Thanks again for wanting to contribute! 🙏
