/**
 * @file runtime-telemetry.js
 * @description Per-model runtime metrics captured by the daemon on every routed request.
 *
 * @details
 *   📖 Why this exists:
 *   📖 SWE-bench / tier scores are static and self-reported by providers — a model
 *   📖 can advertise 82% on SWE-bench and still fail 50% of real requests through a
 *   📖 flaky free-tier gateway. We track what *actually* happens on the wire:
 *   📖 - real success rate (success vs error calls)
 *   📖 - real avg tokens/second (throughput under our real traffic)
 *   📖 - recent calls (last 50, capped) for debugging
 *
 *   📖 Distinct from src/core/telemetry.js
