Crate docgen_diff 

docgen-diff — the doc-diff timeline port.

A pure-logic crate that owns the port of the original SvelteKit/TypeScript doc-diff timeline (~/work/docgen/packages/docgen/src/lib/diff). It keeps libgit2 out of docgen-core (whose pipeline tests stay fast and dependency-light) and mirrors the original’s split between pure diff algorithms (no git) and the git-driven orchestrator.
