78785e54e1 feat: production-grade routing cache + stale detection fixes 
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

c713a4f142 feat: metrics agent for FreeSWITCH and Asterisk nodes 
- pulse-lets-go-agent: collects metrics from PBX nodes via ESL (FreeSWITCH) or AMI (Asterisk)
- AMI client (raw TCP) for Asterisk Manager Interface
- Collector interface: collect, connect, subscribe hangup events, close
- FreeSWITCH collector: show channels, max_sessions, idle_cpu
- Asterisk collector: CoreShowChannels, CoreSettings
- System collector: /proc/loadavg, /proc/stat (CPU idle)
- Failure tracker: sliding window for call_failure_rate
- NATS publisher: pulse.metrics.<node_id> every 5 seconds
- Graceful shutdown, retry logic (5 failures → status=down)
- Template configs for UC nodes (Asterisk) and ses-sip (FreeSWITCH)
