011 invalid module qualifier

// Test 618b: Invalid Module Qualifier (MUST FAIL)
// Validates that short-form module qualifiers like "io:println" are rejected
// Koru does NOT support import aliases - must always use full path

~import "$std/io"

~event test {}
| done {}

~proc test {
    return .{ .done = .{} };
}

// This should FAIL - "io" is not a valid module qualifier
// Correct form is: std.io:println
~test()
| done |> io:println(text: "WRONG - should be std.io:println")
