weiihann d61dd875d8 nomt: add triecompare package and fix sort.SliceStable bug in stem grouping ... Add trie/triecompare/ package with realistic state generation and cross- validation tests proving NOMT produces identical roots as bintrie at scale (10K+ accounts, PowerLaw/Uniform/Exponential distributions, multi-block). Fix a subtle bug in groupAndHashStems: sort.Slice was used instead of sort.SliceStable, causing non-deterministic results when the same account is mutated twice in a single block (duplicate stem+suffix entries need last-writer-wins ordering preserved). Tests: 5 correctness tests + 4 benchmarks + storage footprint comparison. All pass with race detector clean. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>		2026-02-13 00:07:04 +08:00
