Strip <think> blocks from raw predictions before extraction

Browse Source 
Hybrid-thinking gateways inline the reasoning channel into content
wrapped in <think>..</think>; extractors then produced answers like
'3</think>Let me analyze...' (drop em 0.0 with f1 0.5 on samples the
model actually answered). Blocks and stray closers removed pre-extract.
