007 parser dump ast

✓ Passing This code compiles and runs correctly.

Code

// Test: AST dump to JSON
//
// Parses Koru source code and dumps the AST as JSON.
// This enables tools to inspect parsed structure.
//
// Pure Koru - no Zig procs needed!

~import "$std/parser"
~import "$std/io"

const std = @import("std");

// Sample code to parse
const SAMPLE =
    \\~event hello {}
    \\| done {}
;

// Flow: parse → dump → print (pure Koru!)
