📝 How It Works

1. On PR or manual trigger, the workflow checks out the code and installs Ollama.
2. Ollama is started and the qwen3:14b model is pulled.
3. The workflow generates a git diff between the PR branch and its base.
4. The diff is sent to the LLM with a detailed review prompt.
5. The LLM's "thinking process" (if present) is filtered out for clarity.
6. The actionable review is posted as a comment on the PR.
7. Ollama is stopped and the diff is shown for debugging.
