Subject: [PATCH] Fix model selection UI: update descriptions and default to
 Qwen 3.5
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Option 2 description: "Qwen2.5 · Qwen2.5-Coder" → "Qwen 3.5 (Feb 2026)"
- Default choice: 1 (Western) → 2 (Performance/Qwen 3.5)
- Recommended tier logic: use TOTAL_VRAM and match actual tier names
  (4B/9B/35B/27B for Qwen 3.5, not old 7B/14B/22B/32B)
- Users with 6GB GPUs now see the 4B option marked "fast — fully in VRAM"
  instead of having to pick Custom and type model names manually
