/**
 * Ecosystem Benchmark Test
 *
 * Benchmarks context-mode against REAL outputs from popular Claude Code
 * MCP servers and Skills that developers use daily:
 *
 *   - Context7 (documentation lookup)
 *   - Playwright (browser automation)
 *   - GitHub (PRs, issues via gh CLI)
 *   - Dev tools (build output, test output, tsc errors)
 *
 * All fixtures are captured from actual tool invocations — not synthetic data.
 * This provides honest, reproducible benchmarks for the open-source community.
