feat: multi-artifact Lambda (lambda_zips map) — v1.4.0

[eli-the-wizard]

Summary

Adds optional multi-artifact Lambda support via a new lambda_zips JSON map input, allowing repos to deploy N Lambda functions from one Terraform root with shared resources (DynamoDB, SNS, SQS) without splitting roots or migrating state.

Changes

• Additive: single-artifact path (artifact_path → TF_VAR_lambda_zip) unchanged; lambda_zips takes precedence when set
• Added lambda_zips input to terraform-lambda-plan.yml, build-deploy-lambda composite, and terraform-lambda-deploy.yml
• Export logic resolves each lambda_zips value to absolute path and exports TF_VAR_lambda_zips JSON map
• Multi-zip fixture (examples/lambda-multi-fixture/) with 2 functions + offline-plannable Terraform
• lambda-multi-smoke CI job validates end-to-end (build → plan shows 2 functions)
• Docs: README + RELEASING updated with lambda_zips usage, TF contract (variable "lambda_zips" { type = map(string) }), and v1.4.0 notes

Test plan

• ✅ Fixture offline plan shows 2 Lambda functions to create
• ✅ actionlint clean
• ✅ shellcheck clean (Build + Export scripts)
• ✅ Functional export test (multi-map + single-artifact fallback)
• ⏳ lambda-multi-smoke job on this PR (end-to-end validation)
• ⏳ Cross-repo acceptance test (gandalf adoption PR) gated for v1.4.0 release

Terraform Plan

📖 Stack: lambda

Terraform used the selected providers to generate the following execution
plan. Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:
