011 vaxis pump realistic

// Realistic vaxis-shaped event pump — three effect kinds dispatched on a
// deterministic mix, invocation handlers mutating per-host module state.
//
// The interleave mirrors `demos/sandbox/js_target_spike/dispatch_bench.mjs`
// (m = i % 64; resize every 64th, focus every 32nd-not-64th, key otherwise;
// key carries 'q' (113) every 97th event). That makes this fixture directly
// comparable to the hand-rolled JS dispatch strategies in the bench, with
// the same handler work and the same event-count signature.
//
// What this proves beyond 140_010: THREE kinds (not two), real work in each
// handler (counter + sum + xor + conditional quit-counter), so neither V8
// nor LLVM can DCE the dispatch to a tie.
