MIRA-AC behavior shift: hypothesis-distinguishing tests up 16.8% to 28%, stalled tweaks halved

Follow-up data from the same MIRA-AC work: in an LLM-judged study of 400 matched trajectory pairs, the trained policy behaves notably differently:
- Tests distinguishing hypotheses: 16.8% → 28.0%
- Repeated minor tweaks to stalled ideas: 33.5% → 18.8%
The learned policy investigates unresolved uncertainty more often instead of spinning in dead ends.
