Temporary branch is not being cleaned up in case of failure

**Describe the bug**
When attempting to configure ClaudeCode using quick setup `/install-github-app`, but a failure has occurred, it doesn't cleanup the used branch to add the workflow on GitHub.

**To Reproduce**
1. Mark the main branch as protected, prevent direct pushing.
2. Run `/install-github-app`.
3. Failure should happen since the branch is protected.
4. Branch used to add the workflow should be removed.

**Expected behavior**
Cleanup the branch in case of failure to integrate ClaudeCode action.
