Replace all occurrences of zai-proxy.mcp.svc.cluster.local with zai-proxy.devpod.svc.cluster.local in documentation files. Verification: - No old namespace references remain (grep verified) - DefaultConfig pattern is correct (shared parsing in config package) - Dashboard rate tests pass - Comma-splitting verified working Fixed files: - dashboard/README.md - DEVELOPMENT.md - docs/notes/CANARY_PROMOTION_CHECKLIST.md - docs/notes/CANARY_PROMOTION_PROCEDURE.md - docs/notes/CANARY_ROLLBACK_PROCEDURE.md - docs/notes/DASHBOARD_API_REFERENCE.md - docs/notes/DEPLOYMENT.md - docs/notes/metrics.md - docs/notes/TROUBLESHOOTING.md Co-Authored-By: Claude <noreply@anthropic.com>
