- Refactor dashboard/collector/collector.go to use config.GetScrapeTargets() - Refactor dashboard/api/router.go to use config.GetScrapeTargets() - Add dashboard/config/config.go with DefaultScrapeTarget set to devpod namespace - Remove hardcoded mcp namespace defaults from both files Acceptance: No occurrence of zai-proxy.mcp.svc.cluster.local remains in dashboard Go code, both DefaultConfig structs use devpod default, existing SCRAPE_TARGETS env override unchanged.
