/**
 * Minimal unified-diff generator for the carve bridge patch (#998). Emits
 * git-applyable hunks (`git apply`, or plain `patch -p1`) so the whole survivor
 * edit — data sources plus rewired references — lands in one reviewable file.
 * LCS-based; bridge inputs are hand-sized `.tf` files, so O(n·m) is fine.
