ROUND 2 CURATED

Add business-instructions.txt to the Genie Agent.

Do not add benchmark gold SQL to the agent.

Re-run the exact same:
- 14 Chat-mode deterministic benchmarks
- 3 Agent-mode ambiguity benchmarks

Compare scores and inspect which failure patterns disappeared or remained.

Only after Round 2 should you consider example SQL, SQL expressions, functions, or trusted assets.
