## Title

    Reproduction request: Codex turn-diff checkpoint refs under refs/codex/turn-diffs/checkpoints/ may retain large git loose objects without upst

## Body

    What I found:
    Codex Desktop creates refs under refs/codex/turn-diffs/checkpoints/ that store project tree snapshots as git objects in the repository .git directory.
    Reporter measured 8476 loose objects totaling about 101.86 GiB via git count-objects -vH in a zero-commit repo whose refs were Codex checkpoint refs.
    
    Evidence:
    https://github.com/openai/codex/issues/29388 · https://github.com/openai/codex/issues/29388#issuecomment-5159078198 · https://github.com/openai/codex/issues/29388#issuecomment-5913198046
    
    Still unknown:
    Whether Codex Desktop or CLI will add automatic checkpoint GC or move checkpoints out of the user project .git in a future release.
    
    Useful next check:
    Whether Codex Desktop or CLI will add automatic checkpoint GC or move checkpoints out of the user project .git in a future release.
