962bf0312d feat(observability): Phase 6 OTLP tracing + Prometheus metrics endpoint 
OTLP tracing:
- libs/observability/otlp.rs: SdkTracerProvider via HTTP/proto OTLP exporter
- libs/observability/tracing_middleware.rs: Actix-web span with trace_id propagation
- libs/observability/tracing_fmt.rs: JSON fmt + registry.try_init for layered init
- libs/rpc: gRPC method spans via info_span
- libs/agent, libs/room, libs/service, libs/api: structured tracing throughout

Prometheus metrics:
- libs/observability/prometheus_exporter.rs: /metrics HTTP handler + metrics crate
- libs/observability/metrics_middleware.rs: HttpMetrics middleware + AtomicU64
- libs/observability/redis_metrics.rs: Redis counter poller via RedisMetrics
- libs/room/metrics.rs: RoomMetrics (connections, messages, presence counters)

Config env vars: APP_OTEL_ENABLED, APP_OTEL_ENDPOINT, APP_OTEL_SERVICE_NAME

b4024aa690 feat(observability): Phase 6 OTLP tracing + Prometheus /metrics endpoint 
- Add HTTP OTLP exporter (opentelemetry-otlp 0.31) via SdkTracerProvider +
  BatchSpanProcessor + tracing_opentelemetry layer
- Add Prometheus /metrics handler via metrics-exporter-prometheus 0.13
- Replace slog with tracing throughout: HttpMetrics, TracingSpanMiddleware
- Replace .init() with .try_init() to allow OTLP layer registration after
  init_tracing_subscriber()
- otlp.rs: SpanExporter::builder().with_http().with_endpoint(),
  Resource::builder().with_service_name(), .with_attribute(KeyValue::new(...))
- prometheus_exporter.rs: install_recorder(), prometheus_handler(),
  spawn_http_metrics_poller()

81e6ee3d48 feat(observability): Phase 1-5 slog structured logging across platform 
Phase 1: add libs/observability crate (build_logger, instance_id);
  remove duplicate logger init from 4 crates
Phase 2: Actix-web RequestLogger with trace_id; MetricsMiddleware + HttpMetrics
Phase 3: Git SSH handle.rs slog struct; HTTP handler Logger kv
Phase 4: AI client eprintln -> slog warn; billing ai_usage_recorded log
Phase 5: SessionManager slog; workspace alert slog 2.x syntax
