perf: memory optimization — jemalloc, 2 worker threads, Box<str> for datasets

- Added tikv-jemallocator for better long-running memory behavior
- Reduced tokio worker threads from default to 2 (I/O bound workload)
- Switched dataset string fields to Box<str> to reduce heap overhead
- Startup RSS down from 64MB to 38MB
