💡 What: Optimized the `SlidingWindowRateLimiter` to reduce Redis round-trips by batching the `zrange` call into the initial pipeline.
🎯 Why: Previously, the rate limiter performed a separate `zrange` call after the main pipeline to determine the `resetAt` time. This caused unnecessary network latency in a high-frequency component.
📊 Impact: Reduces network round-trips from 2 to 1 for successful requests, and from 3 to 2 for denied requests.
🔬 Measurement: Verified with a new unit test in `packages/cache/src/index.test.ts` that uses a mocked Redis pipeline to confirm the batching logic. Also ran workspace-wide tests and linting.
