Control plane API

REST endpoints under /api/v1 for projects, builds, deploy, promote, and rollback — the same contract as @voicethere/cli. Authenticate with a Bearer API key (vth_dev_* or vth_live_*) or a dashboard session cookie.

Staging base URL: https://app.voicethere.dev/api/v1

Raw spec: /openapi/openapi.yaml. See also session errors for runtime error codes, agent logs for structured logging, advanced voice settings for VAD and barge-in tuning, and agent crash policy for disconnect_all vs restart_child, and CLI login for browser device approval and personal API keys, and Terms of Service acceptance for the CLI/API TOS gate and authentication cache TTL.
