 * Iterative (explicit work stack) so deep import chains never approach V8's
 * recursion limit — the overflow behind #20986 — with no separate recursive
 * form or depth cap. Cycles use Tarjan's `index`/`lowlink`: a module's result
 * is memoized on `_sideEffectsStateGraph` only when it is context-independent
 * (cycle-free, or the root of its strongly-connected component), i.e. exactly
 * when the result cannot depend on which ancestors are mid-walk.
 *
 * The previous walker disabled memoization for the whole walk the moment any
 * cycle appeared (one global `circular` flag). With diamond-shaped graphs that
 * made the walk exponential, so a single circular import could blow up an
 * otherwise-linear graph. Per-module lowlink keeps the cycle-free majority
 * memoized while a cycle exists elsewhere.
 *
 * Caching under `lowlink === index` is conservative: an imprecise lowlink can
 * only skip caching (a later recompute yields the same value), never memoize a
 * state that depended on stack context. `true` is monotonic and always cached.
 * A non-`NormalModule` dependency (e.g. `ConcatenatedModule` re-entering this
 * method) is treated as a taint so its chain is never memoized, and any module
 * already flagged `_isEvaluatingSideEffects` (this walk or an outer re-entrant
 * one) counts as circular, matching the previous walker.
