Preview environments are now end to end and included in paid plans.

- Create a preview from production in under three minutes with **zero cloned
  secrets**.
- TTL expiry runs unattended in the operator's reconcile loop, so forgotten branches are swept
  automatically.
- `data_mode` and `ttl` are first-class on `POST /v1/…/environments`; extend with
  `POST /v1/…/environments/{id}/renew`.
- Usage envelope and caps are readable at `GET /v1/…/environments/{id}/usage`.
