[BUG] AI Suggestion Generation Instability

[Vixel2006]

🧠 Description

The AI suggestion generation sometimes returns errors and behaves inconsistently.
It appears to be unstable under certain conditions, possibly related to data handling or model response timing.

⚙️ Steps to Reproduce

1. Open the AI suggestion interface.
2. Add or modify a bookmark, category, or tag.
3. Trigger AI suggestion generation.
4. Observe that sometimes an error occurs or the suggestion fails to load.

📸 Expected Behavior

The AI suggestion system should generate consistent and stable outputs without throwing errors.

🧠 Additional context

This issue might be linked to concurrency or API response inconsistencies.
We should check backend error logs and possibly introduce retries or better error handling in the AI suggestion generation pipeline.
