* feat(helm): add Prometheus operator ServiceMonitor support The api (port 8888) and worker (port 8889) containers expose Prometheus format metrics at /metrics (verified against app source); the chart had no wiring for them — the worker's scrape annotations are gated behind the unrelated podAnnotations value and the api service had nothing. Add a gated metrics.serviceMonitor block that emits per-component ServiceMonitor resources (api always when enabled, worker only when worker.enabled). Selection labels are configurable for the Prometheus operator's serviceMonitorSelector (e.g. release: kube-prometheus-stack). Also scrape the dedicated worker in the dev LGTM compose stack, which previously only scraped the api on :8888. Verified end-to-end on k3d + kube-prometheus-stack: all three targets (api + 2 worker pods via headless endpoints) discovered and up=1. * fix(helm): address ServiceMonitor review
