Adds BetterQueue alongside Bottleneck in the API section.

BetterQueue is a distributed rate limiter and job queue for Node.js. Unlike Bottleneck, the queue state lives in Redis rather than in the process:

• Cheap limiters. A limiter is a thin handle, so 1000 limiters cost roughly what 10 do.
• Jobs survive a crash. Another process picks up work that a dead worker was holding.
• Cross-process priority. Ordering is computed server-side, so it holds across the whole fleet.
• Delayed jobs. scheduleAt() for work that needs to run later.

The repo includes a benchmark that runs both libraries in separate processes against the same Redis. With 1000 limiters and 51,000 jobs, RSS after the run was 415 MB for Bottleneck and 222 MB for BetterQueue, and throughput was 9,957/s vs 11,456/s.

MIT licensed, TypeScript, 37 tests with CI on Node 18/20/22.
