013 qualified type in branch

// Test: Qualified type references in branch outputs
// Bug: Emitter outputs "mod:Type" literally instead of translating to valid Zig
//
// Input types work correctly, branch types don't.

~import "$std/compiler"

// Event using qualified type in branch output
~pub event passthrough { ctx: std.compiler:CompilerContext }
| ctx std.compiler:CompilerContext

~proc passthrough {
    return .{ .ctx = ctx };
}
