/**
 * Minimal line-diff implementation for nx release output.
 *
 * Replaces jest-diff to eliminate transitive dependencies (pretty-format,
 * chalk, ansi-styles@5) that cause version conflicts for supply chain
 * hardening.
 *
 * Uses @jest/diff-sequences (zero deps) for the core LCS algorithm.
 *
 * Source algorithm: https://github.com/jestjs/jest/tree/main/packages/jest-diff
