LoadLab v0.1.2 - Native Rust & Go Benchmark Engines (Oha & Bombardier)

LoadLab v0.1.2 introduces two high-performance native engines (oha and bombardier) capable of pushing tens of thousands of requests per second with multi-core parallelism, along with a rate-limited mock endpoint for benchmark testing.

🚀 Highlights

• oha (Rust / Tokio / Hyper): Added support for the ultra-fast Rust benchmark engine with native HTTP/2 support, detailed microsecond latency percentiles (p50, p90, p95, p99), and low memory footprint.
• bombardier (Go / FastHTTP): Added support for Bombardier, built for raw HTTP throughput benchmarks pushing 20k–50k+ req/sec without choking the UI.
• Crash-Isolated Child Process Architecture: Both engines execute in isolated operating system processes, taking full advantage of all available CPU cores while keeping the Electron UI silky smooth.

✨ What's New

1. Native Engines in UI

• The Engine tab in the test builder now includes:
• oha (Rust / Hyper / HTTP/2)
• Bombardier (Go / FastHTTP)
• Autocannon (Default)
• loadtest (ab-compatible)
• Artillery (Scenario Runner)
• Both new engines support concurrency (-c), duration (-z / -d), request rate caps (-q / -r), custom HTTP methods, headers, and authentication tokens.

2. Mock Rate-Limited Test Endpoint

• Added /api/rate-limited to test/server.mjs.
• Default threshold: 100 req/sec (customizable via ?limit=N).
• Returns HTTP 429 Too Many Requests with standard rate-limit headers (X-RateLimit-Limit, X-RateLimit-Remaining, Retry-After: 1), allowing developers to test and visualize how apps behave under throttle conditions.
