PLAN stage. P58 fixes the 4-VPC bug: adds a single shared VPC to
terraform/platform, drops the vpc child from the microservice composition
(references the platform VPC via data source), and makes state keys
env-aware (spike/{id}/{env}/terraform.tfstate — stable across lifecycle).
5 tasks: platform VPC, composition update, resolver environment passthrough,
adapter state key + data block emission, tests + regression.
