Generic value tree + reflection serialize/deserialize + JSON bridge (#44) — a self-describing `Value` node (null/int/fixed/bool/str/list/object) with constructors, builders (`Value.add`/`Value.put`) and accessors (`Value.get`/`Value.at`/`Value.count`/`Value.kind`/`Value.as_int`/`Value.as_str`/…). `Reflect.serialize(entity)` walks an entity's whole component set into a value tree (one member per component, each a sub-object of its fields) and `Reflect.apply(entity, value)` writes one back — a `fixed` field becomes a `fixed` node, everything else an `int` node, so the round-trip is bit-exact; the model id rides along under `"@kind"`. `Json.encode`/`Json.parse` bridge the tree to and from compact, stable, diffable JSON text, with `fixed` written as an exact terminating decimal that parses back bit-for-bit. Together they are a one-call save/load for entities and the backbone of data-driven tooling. Written in Ludic and spliced on demand (like Query/Light), so a program that doesn't touch `Value.*`/`Json.*`/`Reflect.serialize` compiles byte-identically and the C-free bootstrap fixpoint is untouched. The general tagged-union/`any` language type remains tracked in #1; this delivers the concrete value tree the serializer needs.
