feat(ai): default to qwen2.5-coder:3b for the sandbox task path

Browse Source 
Reorder _CODER_MODELS to prefer the 3b coder build over 1.5b. The 3b roughly
doubles the ground-truth pass rate on the verify-then-repair native harness
(bench: 7/9 vs ~4/9 over the 9 non-net tasks) at a modest CPU-latency cost,
so it is auto-selected ahead of 1.5b when present. 7b was evaluated and
rejected: too slow to first-token inside the engage window on the CPU-only box.
