v0.0.6

Features

• Recursive types compile statically: self-referential interfaces (interface TreeNode { label: string; children: TreeNode[] }), mutually recursive types, and recursive unions — the AST/tree/linked-list class — now map to native representations. Cyclic values are collected by the cycle collector; JSON.stringify on a cyclic value throws V8's exact circular-structure error; console.log prints Node's circular reference markers; JSON.parse(x) as T validates recursive shapes with path-exact failures.
