Implements a new MCP server that provides read-only access to git
repositories using go-git. Designed for deployment verification by
comparing deployed flake revisions against source repositories.
9 tools: resolve_ref, get_log, get_commit_info, get_diff_files,
get_file_at_commit, is_ancestor, commits_between, list_branches,
search_commits.
Includes CLI commands, NixOS module, and comprehensive tests.
