Deep-path types at scale — ergonomics & benchmarks

One contract (DeepKey / DeepValue / DeepKeyFiltered / ArrayOfChanges / BoolLogic / MathExpr over a large state object), six implementation approaches, measured from 4.7k to 96k paths under two TypeScript engines. The question throughout: what keeps the type-checker (and the editor) cheap as the state grows past ~5–6k paths, where the union approach OOMs.

Path convention: [*] = Record/index key, [n] = array element, .?? = any/never sentinel.
