Sets AWS_SDK_UA_APP_ID in the Terraform provisioner environment so that all AWS API calls made during workspace builds include Coder's AWS Partner Revenue Measurement (PRM) attribution in the user-agent header.

This enables AWS to attribute resource usage driven by Coder back to us as an AWS partner across all deployments.

How it works

• provisionEnv() now unconditionally sets AWS_SDK_UA_APP_ID=APN_1.1/pc_cdfmjwn8i6u8l9fwz8h82e4w3$ in the environment passed to terraform plan and terraform apply
• The Terraform AWS provider picks this up and appends it to the user-agent header on every AWS API call
• If a customer has already set AWS_SDK_UA_APP_ID in their environment (e.g. via coder.env), we don't override it
• Templates that don't use the AWS provider are unaffected — the env var is simply ignored

Notes

• The product code is hardcoded in the source. It may be worth obfuscating this value (e.g. via -ldflags -X at build time) to keep it out of the public repo, though it is technically a public identifier.
• This covers user-agent attribution only. Resource-level aws-apn-id tags for cost allocation are a separate effort that requires template changes.
