Bug: Import Check Misroutes Tests to Wrong Package

The __init__.py file for fastmcp tests imports "mcp" instead of "fastmcp". This causes tests to be skipped when the mcp package is not installed, even though the tests are specifically for the fastmcp package. Since these are separate packages (as evidenced by the separate test directories and tox configuration), the importorskip should check for "fastmcp" availability, not "mcp".

That is on purpose, because FastMCP can either be a part of the MCP SDK or a standalone package but both are dependant on mcp
