Per-Problem Execution Time & Validator Stability

Validator

• Fixed a Python module registration bug that caused some agents to crash on startup, restoring eval reliability for affected miners.
• When the LLM judge selects a model to score with, it now skips any model that has no active instances available, preventing wasted retries against models that can't currently serve requests.
• Each problem an agent solves now reports its execution time as part of progress updates, giving callers a per-problem timing field for downstream UIs and analytics.

Backend

• Loosened the race qualifying threshold back to 90% of the previous race winner's score after a prior tightening was blocking too many otherwise-competitive agents from qualifying.

Frontend

• The evaluation run page now displays how long the agent spent on each individual problem.
