add: Baseline MCP Server to Baseline in the wild

[yamanoku]

Using the Web Platform API, I built an MCP server to ask for the Baseline status.

If people looking at this PR need more context about MCP: MCP stands for Model Context Protocol. See https://modelcontextprotocol.io/introduction. MCP is designed to let LLMs access data and execute actions. A lot of the AI agent discussions that are going around these days are using (or starting to use) MCP.

I've not been able to review the code for the MCP server that's proposed here in depth, mostly because I'm not able to read Japanese, but it seems really cool at a first glance.
From what I saw, this MCP server fetches features from webstatus.dev's API to check whether they are Baseline or not, and makes that information available to whatever LLM wants to use this server.

Approving with a minor suggestion.

Thank you! I am also creating an English version of the README, so please refer to that for more details.
