/**
* Compression engine A/B benchmark CLI (F2.4 / L2).
*
* Runs the deterministic compression engines over BENCHMARK_CORPUS through the C1 harness and
* prints a best-first markdown table, so the default engine can be chosen from real numbers
* rather than intuition. Deterministic and API-free (safe in CI / local dev).
*
* Usage:
* npm run bench:compression # the default deterministic engine set
* npm run bench:compression rtk lite # a specific subset
*
* llmlingua is excluded by default — its real compression needs the ONNX model at runtime
* (pass it explicitly once provisioned; the framework is engine-agnostic).
