custom coordinator bug

// Test: Custom Compiler Coordinator Override
//
// Validates that users can override the abstract coordinate event
// with their own pipeline implementation using cross-module overrides (~mod:event = ...).
//
// The custom coordinator prints a marker, then delegates to standard pipeline.

~import std/compiler
~import std/optimizer

const std = @import("std");
const ast = @import("ast");
const Program = ast.Program;

// Custom coordinator that wraps the default pipeline
// All compiler events must be module-qualified
