Every normalization branch in the loop wrote through `newParentVNode._children[i]`, reloading the property each time. Bind it once and write through the local instead. -5 B brotli (4582 -> 4577), performance-neutral across update, mount, keyed-reorder and hydration benchmarks. This replaces the earlier "avoid allocating arrays for single children" approach from this branch. Passing the single child unwrapped did win 3-7% on update10th1k, but it cost ~3% on first-paint hydration, so it was dropped. For the record, hydrate1k's reported 45-55% regression on that earlier version was a measurement artifact, not a throughput regression: the benchmark does exactly 5 warmup hydrations and times the 6th, and each iteration clones and discards ~8000 DOM nodes, which produces a deterministic periodic slow hydration every ~4-5 iterations. Each build has its own phase. Timing only #6 sampled the patched build's slow phase. Holding the build pair fixed and varying only the warmup count gave -16.8% / +30.8% / +6.4% / +0.9% / -21.8% / +7.0% for hydrations 5-10 (mean ~+1%), while a main-vs-main control over the same protocol stayed flat at +0.2% / -0.5% / -1.3%.
