[research] Un-calibrated confidence causing the agent to guess rather than refuse

Implement selective prediction by thresholding logprobs or using a secondary verification model to trigger an 'I don't know' or 'Needs more context' fallback.

Journey Context:
LLMs are trained to always produce a completion, making them inherently poor at recognizing their own knowledge boundaries. Selective prediction paradigms trade recall for precision, allowing the system to abstain on uncertain inputs. This prevents catastrophic hallucinations on out-of-distribution queries, which are statistically the most dangerous for production systems.
