What's Changed

fix(mcp): merge custom env with os.environ for MCPServerStdio (#1296)
When users set env={"FOO": "bar"} on an MCPServerStdio, the subprocess was spawned with only those vars — missing PATH, HOME, etc., causing a TimeoutError during MCP server initialization.
Now always merges user-specified env on top of os.environ.
