cloud-run.tf + cloud-run-stage.tf: small alignment edits from the
dev-env agent's work to match the actual deployed Cloud Run shape.
runners/startup.sh: 10-line additions from the gitea-runner agent
during initial provisioning - environment setup adjustments
discovered when the runner came up the first time.
stripe-billing.tf: prior-session work that hadn't been committed,
folding it in now to clean the working tree before further changes.
- stripe-billing.tf: Secret Manager resources for all billing IDs:
meters (input/output), plan prices (free/professional/founding),
overage prices per plan per token type
- cloud-run-soma.tf: inject all 13 Stripe env vars into the Soma service
via Secret Manager secret_key_ref; add billing secrets to depends_on
