/**
 * Runtime and DSL compatibility version helpers.

 * `VERSION` is the TypeScript package/runtime version surfaced by the

 * The newest DSL dialect this runtime understands — deliberately NOT `VERSION`.
 *
 * A package version moves for a fixed error message or a rewritten README; the
 * language does not. Tying the two meant every patch release quietly raised the
 * ceiling here while the four ports stayed where the language actually was, so
 * `<tdc version="0.1.3">` ran in TypeScript and was refused with `TDC005` by
 * Python, Java, C# and Rust — the same config, five implementations, two
 * answers.
 *
 * Raise this only when the DSL itself gains something: a tag, an attribute, a
 * value a previous runtime could not have understood. Then raise it in all five
 * at once, and the shared diagnostic case will say so if one is forgotten.
