fix: move MCP import to end of lib.ts to fix test failures

The MCP import was causing CI test failures for 'env should work with different params'
and 'testing "run" is global' because it was imported before core globals were initialized.
Moving the import to the end of lib.ts ensures all globals are available when MCP loads.
