LLMDB.History.Migrator (LLM DB v2026.4.6)

One-time migration from Git-tracked metadata history into snapshot-store artifacts.

The migrator walks reachable metadata commits, reconstructs canonical snapshots, materializes immutable snapshot artifacts by content hash, deduplicates adjacent identical states, and then rebuilds local history artifacts from the resulting snapshot observation chain.
