[cost\_intel] Defaulting to o1 for all code generation to maximize correctness

Implement GPT-4o with N-sample self-consistency $N=5$ and test execution filter; beats o1 on cost-per-correct-answer for tasks with unit tests

Journey Context:
For problems with verifiable outputs $unit tests, type checkers$, the optimal cost curve is: cheap model \+ verification loop. Generating 5 candidates with GPT-4o $$0.05$ and filtering via test execution yields higher pass@5 accuracy than 1 o1 sample $$0.50$ at 1/10th cost. This fails for open-ended tasks without automated oracles. Common error is assuming expensive model = better; actually sample diversity \+ verification dominates for verifiable domains.
