Three-tier routing cache (ESL global -> file -> HTTP) eliminates HTTP
from call path for 2500-5000 concurrent calls. Lua reads cached route
in ~0.1us instead of blocking on api:execute('curl', ...).
Engine fixes:
- recalcBestLocked now skips stale nodes (was 5 min bug -> now ~10-15s)
- PickNodeForCall action_type='node' checks staleness for consistency
- onMetric callback pushes cache on every metric (no ticker delay)
Config:
- stale_threshold_sec default 20 -> 10 (industry standard)
- contrib/ included in Makefile deploy target
- route.lua paths updated for /opt/pulse-lets-go
