/**
 * Streaming value(i) resolvers — compute a single row's value on demand for
 * Engine 2, using the seekable PRNG and the Feistel permutation. Pure: no
 * context, no arrays of length `count`. See
 * `docs/superpowers/specs/2026-07-14-engine2-streaming-impl.md`.
 *
 * - **Exact percent** — place a sorted Hamilton quota plan by `permute(i)`.
 *   The bijection sends exactly the first `counts[0]` indices into the first
 *   category's slot range, so the distribution is byte-exact with NO array
 *   (a "lottery with no tumbler").
 * - **Uniform list pick** — an independent seekable draw per row.
 * - **Counters** — pure functions of `i`.
 *
 * The list-agnostic generators (number ranges, dates, regex, symbols) are
 * resolved at the integration layer by reusing the existing generator on a
 * per-row seekable draw, so their logic is not duplicated here.
