Function export_to_git 

pub fn export_to_git<S: Store, H: BuildHasher>(
    panproto_store: &S,
    git_repo: &Repository,
    commit_id: ObjectId,
    parent_map: &HashMap<ObjectId, Oid, H>,
) -> Result<ExportResult, GitBridgeError>

Export a panproto-vcs commit as a git commit.

Loads the schema from the panproto commit and serializes it into the git tree. If a parent_map is provided (mapping panproto parent commit IDs to git OIDs), the exported git commit will have the correct parent pointers, preserving the DAG structure.

The schema is stored as a JSON file in the git tree. This is the authoritative representation; source text reconstruction requires re-parsing with the appropriate language parser.

Errors

Returns GitBridgeError if VCS operations or git operations fail.
