chore: expand alias template benchmark coverage

 - The benchmark for this segment is a targeted ignored test suite that scores family detection/template rendering coverage for Qwen, Gemma, Llama, Kimi, and the generic fallback.
 - Baseline run 7 scored only `20.0%` because just the generic fallback path passed; Qwen, Gemma, Llama, and Kimi were still rendered through the old generic formatter.
 - Run 8 (`ceb83f2`) added family detection plus built-in template selection inside `compat.rs` and immediately raised coverage to `100.0%` (5/5 passing), making it the current best for segment 1.
+- Segment 2 raises the bar by checking stronger Llama structure, especially whether system+user are merged into the first instruction block and whether the prompt avoids leaving an open `[INST]` prefix at generation time.
+- Run 10 (`fd6d35e`) hardened the Llama renderer with a dedicated formatting path that folds pending system/developer context into the next instruction block and eliminates the dangling open `[INST]` suffix, raising segment 2 from `71.429%` to `100.0%` (7/7 passing).
