feat: add routing configuration with RPM caps (ornith syslog-auto: 40→60)

- Strix Halo ornith RPM increased from 40 to 60 inside syslog-auto pool
- Prevented unbounded ornith traffic when multiple agents use syslog-auto
- Direct ornith remains at RPM=40
- All models verified healthy (ornith 80ms, gemma 110ms, qwen 840ms)
- Added full routing table to gpu-fleet contract

+### Why ornith RPM Is Capped
+- Direct: 40 RPM (tight) — Strix Halo is shared with compression tasks
+- Via syslog-auto: 60 RPM (moderate) — prevents flooding when multiple agents use syslog-auto simultaneously
+- Combined max: ~100 RPM across both paths — Strix Halo can sustain this at 80°C
