Subject: [PATCH] Bump Ollama model to qwen2.5:1.5b for better instruction
 following

The 0.5b model was too small to reliably follow simple prompts like
'Say Hello World', causing test assertion failures. The 1.5b model
follows instructions more reliably while still being small enough
for fast CI pulls (~1GB).
