## Title

    Reproduction request: Codex turn-diff checkpoint refs may keep project snapshot git objects without garbage collection; a reporter says cleanu

## Body

    What I found:
    A reporter measured about 101.86 GiB in loose objects (8476 count) with only Codex checkpoint refs and zero commits, and stated total project size grew from about 5.7 GB to about 140 GB.
    The issue reporter lists git gc --prune=now as a prune workaround and states cleanup reduced size from 140 GB to 5.7 GB.
    
    Evidence:
    https://github.com/openai/codex/issues/29388 · https://github.com/openai/codex/issues/29388#issuecomment-5913198046 · https://github.com/openai/codex/issues/28241
    
    Still unknown:
    Whether current Codex Desktop App Store builds after 26.616.51431 prune superseded checkpoint refs automatically.
    
    Useful next check:
    Whether current Codex Desktop App Store builds after 26.616.51431 prune superseded checkpoint refs automatically.
