070 universal wildcard concrete

✓ Passing This code compiles and runs correctly.

Code

// Test: Universal Wildcard Tap with Metatype
//
// Demonstrates that universal wildcard taps (*:*) must use metatypes
// like Profile, Transition, or Audit (not concrete branches).
//
// With metatype, the tap can observe any event/branch combination
// and access the Profile metadata (source, branch, destination).

    return .{ .done = .{} };
}

~proc goodbye {
    std.debug.print("Goodbye\n", .{});
