fix: add micro-throttle for Linux performance parity

Linux runs too fast compared to Windows/Wine, causing vehicle queue
backup (~44% completion vs 95% on Windows). Adding microsecond delays
via LockSupport.parkNanos() achieves 92% completion.

- 50μs delay in SocketConnection send/receive
- 100μs delay in CoordinatorProcess vehicle generation
