Describe the bug

Yesterday I deleted an index.md file but forgot to update the navigation.redirect property in _dir.yml. After committing the changes, I went to sleep. This commit ended up building for a full 6 hours in GitHub Actions before GitHub forcibly terminated it.

This is a critical point to note—it rapidly depletes your free GitHub Actions quota.

The build got stuck during pnpm run generate and ran for 6 hours.

See the case here:

In this commit, I renamed index.md to home.md, but I forgot to update the navigation.redirect property in _dir.yml.

1. Ensure your folder contains _dir.yml and index.md, with the navigation.redirect property in _dir.yml pointing to index.md.

2. Run pnpm run generate to trigger the build.

3. It should generate quickly.

4. Rename index.md to another name (e.g., home.md).

5. It fails to generate even after 10 minutes (or even 6 hours).
