/**
 * Dataset-Driven Eval Bench for NodeBench MCP Tools
 *
 * Tests MCP tool orchestration against REAL open-source task descriptions
 * from SWE-bench Verified (500 human-validated GitHub issues).
 *
 * Each task runs through the FULL agent pipeline:
 *   Recon → Verification → Eval → Quality Gate → Learning → Flywheel
 *
 * This proves the tools can orchestrate real-world development workflows
 * end-to-end, not just pass unit tests in isolation.
 *
 * Dataset: SWE-bench Verified (princeton-nlp/SWE-bench_Verified)
