The current conversion process mandates an empty repository for a clean start. This presents a barrier to performance optimization strategies. This change introduces the ability to pass a repository root commit hash. This is necessary to support the immediate next commit (Incremental LFS conversion), which uses a `.gitattributes` file and LFS pointers to bypass the slow, full-history rewriting often required on large non-empty monorepos (100GiB+, 1M+ files). The immediate benefit is allowing conversion to start when a non-empty repo already contains an orphan commit, laying the groundwork for the optimized LFS conversion feature.
