Three pass-2 guards (mirrored in the --dedup-llm pair collection): block merges
when labels' embedded numbers differ as zero-padding-insensitive multisets;
block cross-file merges of file-anchored rationale/document nodes (same-file
still merges); and score cross-file long labels on plain Jaro instead of
Jaro-Winkler so the prefix bonus can't fabricate merges of shared-prefix but
token-divergent entities (jest-native vs react-native), while genuine cross-file
duplicates still clear Jaro and same-file near-duplicates keep Jaro-Winkler.
