The character encoding of the stdin/stdout streams in Python is platform-
dependent. On Windows it will be something weird, like CP437 or CP1252,
depending on the locale. This change ensures that no matter the platform,
UTF-8 is used.
We will be a bit more low level and expect callees to import mcp.types
instead of relying in re-exported types. This makes usage more explicit
and avoids potential collisions in mcp.server.
