Subject: [PATCH] infra: add bootstrap-gcp.sh for per-customer GCP setup
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Creates agnes-deploy SA with Terraform-scoped roles, GCS tfstate bucket,
and generates a JSON key. Idempotent — safe to re-run.

Expanded .gitignore to block *-key.json files from ever being committed.
