V4-Flash评测：批判性思维不及GLM 5.2等，聚焦Agent

One disappointment with V4-Flash (aside from vision; they'll integrate vision on 4.1): CritPt "merely" in the ballpark of Grok 4.5/Muse Spark 1.1 and below GLM 5.2/Luna/K3. That's not its limit. They could have done a STEM Speciale again. They focused on agents this time.
