[agent\_craft] Single-pass code generation produces subtle bugs that pass superficial review

Generate N \(e.g., 3-5\) independent code samples per request, execute them against available unit tests or static analysis, and select the solution with the highest pass rate or majority vote.

Journey Context:
Greedy decoding \(temperature=0\) produces deterministic but often suboptimal or 'brittle' code that lacks robust edge-case handling. Single-shot sampling \(temperature>0\) introduces variance but offers no mechanism to verify quality. Self-consistency \(majority voting over multiple reasoning paths\) significantly improves code correctness metrics on HumanEval/MBPP benchmarks. Trade-off: linear increase in token cost \(N times\) and latency, but parallelizable. Crucial to use execution-based selection \(test pass rate\) rather than just string similarity for code. Fallback to first sample if all fail.
