Koichi ITO f6f064ab71 Add instructions support to MCP::Server 
The response of the `init` method can include `instructions`.
https://modelcontextprotocol.io/specification/2025-06-18/basic/lifecycle

`instructions` appear to be supported starting from the 2025-03-26 specification.

- https://modelcontextprotocol.io/specification/2025-03-26/basic/lifecycle (supports `instructions`)
- https://modelcontextprotocol.io/specification/2024-11-05/basic/lifecycle (does not support `instructions`)

If `instructions` is used with an unsupported protocol version, an `ArgumentError` will be raised.

As additional context, the TypeScript SDK also treats `instructions` as optional.
