perf(trie): use Arc<BranchNodeCompact> to reduce memory cloning in TrieUpdates#84
Conversation
…ieUpdates Replace owned BranchNodeCompact with Arc-wrapped nodes across trie data structures. This optimization significantly reduces memory allocations during block aggregation in RPC caches by sharing nodes instead of deep cloning ~112-byte structures. Impact: ~3x faster extend_ref() calls (440µs vs 1,357µs for 1024 blocks) and 14x memory reduction per node (8 bytes Arc pointer vs 112 bytes full clone).
