happy5318 a57d576805 fix: make prefixed Qwen detection positive-only to avoid shadowing hybrid IDs
Gate review found that the broadened token-prefix check caused
deepseek-r1-distill-qwen2.5-bakeneko-32b to enter the Qwen branch
(qwen2 token), return False, and prevent the DeepSeek detector from
running — a silent regression.

Fix: split into two phases:
1. Positive-only scan: any token matching qwen(\d+) with major >= 3
   immediately returns True. No False path — Qwen 2.x in hybrid IDs
   falls through to subsequent detectors.
2. Terminal guard (original behavior): standalone "qwen" token or
   normalized.startswith("qwen") still applies the 3+ gate with
   return False for 2.x, since those ARE pure Qwen models.

Add regression test for deepseek-r1-distill-qwen2.5-bakeneko-32b.
