002 emitter wrapper

// Test: Emitter wrapper import and handler generation
// This verifies that:
// 1. $std/emitter module exists
// 2. emit.program event can be imported
// 3. Handler code generates without errors
// 4. Backend compiles successfully with emitter wrapper
//
// NOTE: This is a COMPILE-ONLY test. Runtime usage requires ~build.requires
// See test 995 for the runtime usage pattern (documents missing ~build.requires feature)

~import "$std/emitter"

const std = @import("std");

// We don't actually call emit.program here - just verify it exists and compiles
// The import itself proves the wrapper is available and generates valid code
