Local Helm charts currently enter the image-build flow even when they deploy prebuilt images. A missing default Dockerfile can therefore prevent a native Helm deployment.

Add helm.skipImageBuild: true for native Helm services that use prebuilt images. Omitting the option or setting it to false preserves existing behavior. The option rejects service-level Docker build settings and removes inherited Docker defaults for that service.

Chart-only deployments still resolve the chart repository's Git revision and deploy the accepted revision. Missing local chart repositories and unresolved revisions fail the deployment. YAML types, generated schemas, documentation, and regression tests cover the new option.

helm:
  deploymentMethod: native
  skipImageBuild: true

Validation:

• 353 tests passed across eight deployment, configuration, schema, and native Helm suites.
• Server TypeScript check and changed-file ESLint and Prettier checks passed.
• Generated JSON schema checks covered valid and invalid configurations and preservation of existing defaults.
• git diff --check passed.
• No live deployment was performed.
