Module git_layer 

Git-based version control layer using gix. Provides in-process commits, logs, tags, restore, and diffs.

RFC-013 Improvements

• B1: Signature captures fresh timestamp per commit (not OnceLock cached).
• B2: restore_file traverses nested paths (e.g. audit/2024-05.audit).
• D1: CommitContext enables per-agent author tracking.
• D2: diff_commits / file_at_commit for Ouroboros evaluate.
• D3: Removed hex round-trips; list_tags uses Category::Tag.
