fix: remove vestige-agent from workspace (not shipped), improve reasoning chain output

- Removed vestige-agent and vestige-agent-py from workspace members
  (ARC-AGI-3 code, not part of Vestige release — caused CI failure)
- Improved deep_reference reasoning chain: fuller output with arrows on
  supersession reasoning, longer primary finding preview, fallback message
  when no relations found, boosted relation detection for search results
  with high combined_score
