codex - 💡(How to fix) Fix Codex IDE extension in Cursor hangs when workspace root accidentally becomes a large unborn Git repo at $HOME

Cursor Git opened /home/ubuntu as a repository.
git status -z -uall was repeatedly cancelled.
The repo had no remotes and branch/merge-base lookup failed.
Codex emitted repeated IPC initialization timeouts.
Codex Git repo watcher failed with ENOSPC while watching paths under /home/ubuntu.
Codex Git branch prefetch commands ran with cwd=/home/ubuntu and failed.

### What steps can reproduce the bug?

1. Use Cursor connected to a remote Linux server.
2. Open a workspace rooted at or operating from `/home/ubuntu`.
3. Have many unrelated directories under `/home/ubuntu`, including caches, build outputs, and several project repos.
4. Accidentally run:

cd /home/ubuntu
git init

5. Open or reload the Codex IDE extension panel in Cursor.
6. Observe that Codex chats do not load / the panel appears stuck.
7. Remove the accidental home-directory repo:

rm -rf /home/ubuntu/.git

8. Observe that Codex starts loading chats again immediately.


### What is the expected behavior?

Codex should not hang or fail to load chats when the editor workspace root accidentally becomes a very large, unborn Git repository.

At minimum, it should degrade gracefully by doing one or more of:

- avoid recursively watching the entire home directory as a Git repo;
- avoid blocking chat hydration/startup on Git repository metadata;
- detect the no-remote/no-commit/no-branch state and continue without Git metadata;
- surface a clear warning such as "workspace root is a very large Git repository" instead of leaving the chat UI stuck;
- recover after watcher or Git commands fail.

### Additional information

Installed extension path on the remote host:
/home/ubuntu/.cursor-server/extensions/openai.chatgpt-26.5513.21555-linux-x64

Remote host:
Ubuntu 24.04.2 LTS
Git: 2.43.0
Workspace/root path: /home/ubuntu

I intentionally did not attach full raw Codex.log files because they may contain private prompts, conversation IDs, local paths, and extension state.

Workaround:
rm -rf /home/ubuntu/.git

I am not asking Codex to support using a whole home directory as a normal Git repo. The request is for the IDE extension to fail gracefully and not block chat loading when the IDE accidentally detects such a repository.
