fix: pin GKE deployment examples to SIE 0.8.2

[mamayer19]

The GKE examples select an older SIE chart or paths that are unavailable from this standalone module. Use published chart 0.8.2 with its matching GKE overlay and versioned service/worker images, including the Artifact Registry mirroring instructions.

Forward the module's existing model-cache Helm arguments from the development example so the documented installation also configures the required payload store. Use the existing service-account email output for the Workload Identity annotation; the separate precomposed key=value output keeps its current behavior. Terraform module and provider versions remain unchanged.

Validated with Terraform 1.14.9 formatting, backend-disabled initialization and validation of the module and example; TFLint 0.64.0; and Helm 3.16.4 lint/render of the published chart with both public and custom-registry image settings. The rendered images, workload identity annotation and payload-store URL match the documented configuration.

Summary by CodeRabbit

• Documentation

  • Clarified image-mirroring steps, chart overrides, custom model profile upgrades, and the independently versioned Terraform module.
  • Updated deployment examples to pass the email-only Workload Identity service account output to Helm, and documented the separate precomposed annotation output and model-cache arguments.

📝 Walkthrough

Walkthrough

The README and dev-l4-spot example now reference the published SIE Helm chart version 0.8.2 and its GKE overlay. The example exposes Terraform outputs for the service-account email and model-cache Helm arguments.

Changes

SIE chart 0.8.2 deployment

Layer / File(s)	Summary
Published chart guidance README.md	The README links to the published 0.8.2 chart and uses its GKE overlay in deployment commands. It documents image-mirroring steps, chart image versions, and guidance for custom model profiles.
Example deployment commands examples/dev-l4-spot/README.md, examples/dev-l4-spot/main.tf, outputs.tf	The example installs chart version 0.8.2 with its GKE overlay. It passes the email-only sie_workload_service_account output as the Workload Identity annotation value and passes model_cache_helm_args. Terraform exposes both outputs.
